Look for a ground rod near the electric meter, the ground rod may be a few inches above ground or totally buried. There is a clamp that attaches the house ground wire to the ground rod. Make sure that the clamp is tight and that the wire is not loose. As far as outlets not working, it could be as simple as a tripped breaker, if not you could have a fire hazzard!

The previous post is what you should do for checking the connection to earth. Ground loops are more difficult to find. This is where a 2nd connection is made to earth-ground. It happens for example when an installer mistakenly installs a grounding block for coax and grounds it to an antenna mast or even worse puts another rod in the ground. On the other end, the coax is connected to the ground of the receiver and you now have a grounding loop.

On the outdoor outlets & garage this is most likely caused by a tripped or bad GFI. Code requires all outdoor, garage, bathroom & kitchen outlets to be on GFI circuits. These can be found in the circuit breaker boxes, but more commonly they will be on a power outlet receptacle. The GFI may not necessarily be one of the outside outlets and one of these can control several outlets.

GFI' will have a test and reset button. If the reset button is popped, push it back in. If it doesn't stay in, then you have something wrong with the wiring or the GFI has gone bad. In this case you might have a bit of a treasure hunt to find what is wrong. The above grounding loop issue can cause it.

Lots of my friends share your opinion about surge protectors being useless. However, I was made a believer in 2004 when a lightening strike blew a foot-wide hole through my roof (far away from any vent or other metal). Shingles were scattered all over my lawn but no fire, thank goodness. I didn't have a surge protector for my entertainment center and everything (TV, VCR, DVD player, and AM/FM receiver) got fried (everything was plugged in, but turned off). My desktop CPU, monitor and printer were on a surge protector. The surge protector itself was toast, but did its job, and the PC and printer were unharmed and I used them for years with a new surge protector, plus another one I bought for the entertainment center's new equipment.

It's an interesting anecdote, but my reply is that it's more likely having to do with the fact that AV equipment is never truly turned off whereas computer equipment is. I'll also add that computer equipment is generally better built depending upon the manufacturer and/or type. When I was in product engineering for DP equipment one of the tests we had to pass was an electrostatic test were 50,000V was pulsed into the shielding and while the test was going on the device had to continue to operate without error. A bitch of a test that kept many a engineer, including myself, up all night. Even more so if you accidentally touched the machine while it was connected to the vanes.

Probably the same place they did last time. And the same place that the horrible feed on WSLS Roanoke is coming from. The video and audio were out of sync on WSLS, too.

CSN-MA is the only place to see it in HD. And, when I tune to CSN-MA, it shows the "This program is not available in your area. We have found it on channel 10, but it is not in HD. Would you like to tune in anyway?" message on Directv. Sickening.

WSOC is providing the only feed they have available. They normally provide HD feeds when possible.

And the ABC Nascar race looks very good in HD tonight on WSOC 9.1.

It is sad that they had a poor 4x3 feed and the HD feed looked really good.

Is anybody having problem with 46 wjzy. I was watching machal's navy this morning the picture froze then went to no signal my meter on my digital turner is flicker between bad to halfway good. I been getting strong signal for 46 with my indoor Antenna
post #6341 of 7653
I haven't really been watching WJZY that much since they moved to Fox & Antenna TV has been running the same shows for the last 2 years but I tuned it a little while ago and it seems more than fine here.
post #6342 of 7653
Thanks blackcat6

I still getting no signal and I try adjust my Antenna a bit no luck unless they reduced their power a bits

Probably due to atmospheric conditions this morning. For some reason those side mounted flat panel antennas like WJZY are more subject to weather issues than WBTV which is omnidirectional top mount stick antenna. But normally I get WJZY and WBTV at 100%. I would suggest a better indoor antenna such as Terk HDTVa, or a Clearstream 2V from Walmart. Or even the Clearstream 1, but the 2V adds VHF for 7 and 13.
post #6344 of 7653
Not with the Charlotte channels, but I have been seeing fluttering today on channels I uNEVER see it on. There has been a lot of stuff cutting in on the radio, too, from other places. The atmosphere must be letting interference in. It's quite annoying!
post #6345 of 7653
Update: WJZY signal strength does appear to be a bit down today compared to normal. Around 90%, whereas normally 96-100% with attic antenna and preamp. WCNC is 92-96%, and WBTV is 98-100% at my location this afternoon. WMYT also 92-96%. Everything is about normal, except WJZY a bit weaker. But could be weather conditions.

Yes same here. That's why I think strange atmospheric conditions today. I was getting all sorts of radio interference in the car this morning. Strange distant stations drowning out locals. I like to listen to Bob and Sheri, but they changed their omnidirectional pattern for 107.9 about 8 years ago. Now subject to interference from Rickey Smiley on 107.9 from Atlanta. But weird how I can sometimes get the analog 107.9 from Georgia, then the HD 107.9 from Charlotte takes over perfectly clear. In the car. But in the house, I can adjust the rabbit ears and hold onto the Charlotte 107.9. Wish WLNK would go back to their omnidirectional pattern, as they used to have an outstanding signal in the western Carolinas. Now they want to focus the signal east of Charlotte, so it is not as good as 95.1 and 96.1 to the west.
post #6347 of 7653
I vote for weather. On my outdoor 4 bay, not amplified, twin lead connected antenna, I'm getting full strength from WJZY. Excellent SQ too. I'm about 16 miles from the transmitter.

I'm considering upgrade my indoor Antenna in next few months to one of those monoprice HDTV Antenna as the reviews for that antenna is good.

Update I got 46 back few minutes ago

There is a Monoprice double loop amp antenna that may be ok. But I still recommend Terk HDTVa because it has good UHF element as well as rabbit ears for 7 and 13. And amp if needed, but can also turn off but keep plugged in. Go to HHG and try it out. Can always return. But ask them to price match Amazon or lowest price. They sold me one for $20 a year or so ago. Not worth $69.
post #6350 of 7653
That terk is in reality a Silver Sensor (been around for a long time) with some rabbit ears + unknown amp. I don't think amps on set top TV antennas are worth it, unless you have really noisy receiver in your TV. It's definately not worth $69, and I'm not even sure about $20. "Pretty" antennas like that have a fundamental problem. They look good so you can sit them near the TV, but fundamentally you don't want them near a modern LCD or plasma, hence the money for looks is wasted.
post #6351 of 7653
I have tried the Terk HDTVi and HDTVa and they perform well. Good silver sensor design. Plus rabbit ears. Although overpriced. But it is those Terk flat panel designs that are questionable. Those emphasize aesthetics over functionality.
post #6352 of 7653
I have the Terk HDTVo. It's only like 10' off the ground since I live in an apartment. I live in Burlington and get Raleigh (60 miles) and Greensboro (25 mi) just fine. WGPX is the strongest at 90% from behind the antenna. WUNC, WRAL, WCWG, WUVC, WLFL, and WGHP all show over 70% on the LGTV signal meter. Many others are 50-60%. Usually, above 35% is a lock. The antenna is pointed at the Raleigh towers (WTVD is VHF and is therefore "picky" so I point it that way). All of the Raleigh channels and most of the Greensboro channels come in fine without moving it. I can't get WXII to come through, though, no matter what. That is a terrain issue, since I have to point through a hill to it. In the winter, I can get WSET and WDBJ at 85 miles but that requires me moving the antenna. WDBJ comes through during the summer sometimes, too. Those two are hit or miss for quality, but I suspect the last three stations I mentioned would be better if the antenna was higher. WGSR LP from Reidsville comes through from behind the antenna, although not well in the summer. It does show 40% if I point right at it.

I have the opposite experience at my location. 95.1 and 96.1 are two of the weakest stations whereas 107.9 is consistently one of the best performers at my location (almost 70 miles northeast of the transmitter in Dallas). No big surprise, my car radio outperforms my living room AVR across all radio stations.

My belief in surge protectors was confirmed in June 2006. I still remember a very bad thunderstorm that took place back then. I had all of my AVR equipment on a surge protector with the exception of the subwoofer that I owned at the time. Needless to say, the subwoofer got fried while my other equipment was saved. I go for the more expensive models that have multiple cable and phone jacks too. Basically, I don't let anything make contact with my electronics (whether it's phone wire, cable, or electrical) until it first passes through my surge protector. Surge protectors are a good investment; and I wouldn't do without them.

I also believe in grounding outdoor antennas to the electrical ground of the home. It just makes good sense and doesn't have to cost that much money. I am no pro with electrical grounding but got some assistance from someone else when I got my outdoor Winegard installed a couple of years ago. Funny, though when I was growing up in the 70's, it seems like most people in the neighborhood did not bother with any sort of grounding. And they certainly didn't think about such things as surge protectors. Then again, back in those days, people didn't have as much expensive equipment either.
post #6355 of 7653
It's all relative. I do remember when a console color TV which would have been connected to an antenna would easily cost the equivalent of a 1.5 month's wages for the average person in the USA. Did you want a clicker (remote control) for it? Add another week's wages. A "stereo" or hi-fi system, also in a console, would cost you a month's work. Today's electronics are dirt cheap in comparison. You are correct however there were no surge protectors yet I don't ever remember hearing about these devices getting fried by lightening. IMO, it's because they were better built & surge protectors do not protect against lightning.

Surge protectors don't protect against lightning for 2 reasons. In a direct hit it doesn't matter. Lightening has so much potential that it can travel through air. A surge protector is useless here. It will be turned to charcoal just like everything else between the lighting and the earth. In a near field hit (more common) lightning damage comes from electrical induction. In this case the magnetic field from lightning will generate current on any conductor actively connected to ground. This includes everything behind the surge protector. There is no defense against this from happening except to NOT make your home attractive to lightning. (It's why they don't put lightning rods on homes these days.)


"I also believe in grounding outdoor antennas to the electrical ground of the home."

Unfortunately people often get this one wrong. Keep in mind that when discussing an antenna there are two different conductive paths, and they should not be connected together. The first is the mechanical system holding the active elements. This includes the mast, the reflector, mounting bolts, etc. If you ground this part of the antenna system, it should be done with it's own grounding rod and not connected to anything else and especially not the house ground. If you connect it the house ground, you now have a grounding loop. and most likely made your home more attractive to lightning.

The second ground is with the coax shield. It's part of the driven portion of the antenna. When you connect the cable to your TV, HTPC, etc, it will be connected to house ground internally by the device. If you add a coax grounding block then it should only be bonded directly to the house connection to earth at the breaker box.

I think any antenna recommendation should probably be qualified with what it is being used for. Metro Charlotte reception requirements with it's two antenna farms on almost opposite sides if the city (what's up with that anyway) vs that of picking up channels from CLT 50+ miles away will be quite different. One person might find it acceptable to make periodic adjustments when the channels changed while another wants a cable TV type experience.

Yes you are correct. In the immediate Charlotte metro, you will need to find a sweet spot between the 2 tower farms. Perhaps something less directional like a CS2-V or a DB4/4221 would perform better there. But it would have been nice if all Charlotte signals had moved to Dallas, as some cities have all transmission towers in the same general area. Plus the 2000ft height possibly gives those signals an overall wider coverage area.

Well I remember riding in the car around Winston and both 95.1 and 107.9 came in good there. As well as 103.7 and 104.7. The directional pattern of 107.9 now favors east of Charlotte, whereas 95.1 is more omnidirectional. But I think 95.1 may have reduced their transmitter a bit in recent years, not sure. 96.1 has a null to the east to protect a Raleigh signal on the same frequency, so reception in Winston will be spotty. And 103.7 and 104.7 have their transmitters on the east side of Charlotte, providing a good signal to the east. Plus, 103.7 also has a more powerfull transmitter, and I can even receive it with rabbit ears here in Greenville, SC. And I get 107.9 fine with rabbit ears in the house, including the HD Radio signal. Just spotty in the car. And if you get a clear signal from 96.1, the sound quality/audio fidelity is very good. Much better than 95.1 which still speeds up the music.

I'm sorry to say this is flat out wrong advice - having a background in radio/electronics and having a tower at my home - it is part of the NEC code to have all grounds tied together. This is so the potential of everything rises and falls the same. The issue of having seperate ground rods not tied together is there can be a potential difference and this causes the damage.

This is why on the antenna packaging, and any TV manual they show the antenna being tied to the service ground.

95.1 now has co-channel competition, if you will, in the eastern Triad. AM 920, WPCM Burlington, is now also on 95.1 FM. My TV antenna pulls in both 103.7 and 106.5 on my home theater, although neither in stereo. 96.1 is WBBB Raleigh here, which comes in fairly well, although not the best of the Raleigh stations, probably to protect the Charlotte 96.1. 107.9 is there, but several other indiscernible stations cut into it, except for the extreme southern end of Alamance county.

A friend less than 15 miles south of me gets WSOC-TV OTA just fine, and a fluttery-but-never-really-watchable WBTV. He is on top of a slight hill but that's impressive. Gotta be 85 or 90 miles out to WSOC!
