I have details of the LP here:

http://www.aa6g.org/Lp/lp.html

The page needs a little updating since I would only recommend the 12 element design.

The VHF wideband yagi is a special design by Brian Beezley and does not appear on his web page but it is similar to this FM yagi:

http://www.ham-radio.com/k6sti/100.htm

It uses a coax balun. I can provide the exact construction details. A picture of it is attached.

I have 2 extra log periodics and the VHF yagi sitting on the ground here unused. They all need a tiny amount of work on the feed to ready them for a permanent installation. I can't offer them for sale here but if someone wanted to discuss getting one I can be PM'd.

This wet weather sure has put a lid on the strength of the more distant signals. Last night I was only able to receive two stations from Walnut Grove - KMAX 31 and KQCA 58. The rest were below the cliff edge. Signals from up north - 22, 50 and 68 and Mt. Diablo - 42 and 52 were all lower than normal. South Bay signals were about normal level, except that channel 1 was below the cliff edge. What a change from just a week ago!

I just got my Dish Hopper OTA module yesterday and I note the same thing up in Rohnert Park. Signals are down about 10 points from what I've seen in the past. I am picking up 51 channels however....
post #8944 of 10422
As always with this sort of weather signals have been nominal. No issues with Walnut Grove stations. CH's 7, 9 and 32 are in but only about 17 dB SNR while 44 is the best around 23 dB SNR. The only unusual station was KSEE sitting 1 dB above the cliff.

Hi,

 

I just noted that KQED RF 30 was off the air. (10:20 AM)

 

KQED DT9 planned OTA outage, Tues 11/20 8am-10am(ish)

November 19, 2012 · Posted By Red Dana · Filed Under KQED · Comment

Due to installation of new equipment, KQED’s Over the Air tranmission on DT9.1, 9.2 & 9.3 will be interrupted Tuesday 11/20 at apx 8am. Hopefully all work will be completed by 10am, but might run as late as 11am.

Most tuners should automatically restore the signal once it’s back on air. This work should not affect viewers receiving their signal via cable or satellite.

KQED Plus partial outage, early Tues 11/20 midnight-2am

November 19, 2012 · Posted By Red Dana · Filed Under KQED Plus · Comment

Due to overnight installation of new equipment, the feed of KQED Plus to DirecTV, Dish TV, and Astound Cable will be interrupted late Monday/early Tuesday apx midnight-2am. All 3 services will restore their signals as soon as the installation is complete.

This work should not affect Comcast Cable or Over the Air viewers.

KLFB

There haven't been many changes to any stations recently but here's one minor change that I noticed. KLFB has moved to a different location on Mt. Toro. They're now on the KION tower and a little lower. That means I can no longer receive them all the time. A small move made a big difference here.

Lots of enhanced signal conditions going on all day today. I logged KCVU 20 from Paradise as a new DX station tonight. KHSL on 43 was also coming in but that's not a new one.

UHF-20 has open tv markets between active stations...... ( Chico-used.....Sacramento-open.....Fresno...Used ) .....and so on.
On the other hand....
VHF - 9 seems to be used in almost every tv market.... Most used channel in California ?
post #8949 of 10422
There are four full-power stations in the whole state of California that operate on VHF channel 9. I didn't count the number of the other classes of licenses, permits, or applications. Channels 7, 34, 36, & 43 also have four licensed full-power stations in the state.

You can play around with the searches at http://www.fcc.gov/mb/video/tvq.html yourself to see what's out there.
post #8950 of 10422
Full power station(s) is one thing.. Market coverage is another. KVIE-9 in Sacramento has like 70% coverage in the bay area. (2 tv markets) not including Fresno
In most places, with a large outdoor VHF antenna. Channel 9 comes in.
Sacramento, Chico, Bay area, ...... are 3 television markets (In northern California) alone.
The VHF channel itself has distance that a UHF station would lack.

So it's quite possible that 4 full power ch 9's could cover over 8 tv markets in California alone at a minimum.
post #8951 of 10422
I'll leave it to you to satisfy your own curiosity using the tool I indicated plus TVFool, Trip's coverage maps, etc.

I clearly stated the scope of the data I provided.

Hi,

 

I did a lot of searching and the only hit I found was the one referenced.

 

Nothing in the place that that announcement should have appeared. It must appear there for me to truly believe.

 

http://sharepoint.smccd.edu/SiteDirectory/generalservices/Lists/Bid%20Announcements/DispForm.aspx?ID=18

 

I posted the information on [HDTV-in-SFbay] and the KCSM person there did not respond.

 

It may have happened, but it also may just be another attempt for Media Alliance to get the information they want.

 

It is very strange but the two remaining bidders are headed by "A_Nani_Mouse" AFAIK.

 

(NOT ME)

This reference has additional information....
But not much...and it doesn't address the question of what went wrong in the negotiations with the previous top bidders. Instead, it devolves into an unrelated discussion of CSM Board elections. Oh well. Thanks, anyway.

Hi,

 

What went wrong was what I have been saying for years now. NO other non commercial station that relies on viewer pledges can exist within KQED's signal range.

 

KMTP tried pledging for about six months and then gave up. Where their money comes from now is a puzzle for me.

 

We all know what happened to KTEH and it’s other station.

 

I have already suggested that the time is too soon for KRCB, but it’s time will come to merge.

 

Up front money and a plan for money coming in to keep the station going was IMHO what the two bidders could not prove.

 

------------------------

What is the future for KCSM? Hard to predict but the upcoming big RF crunch will show the way.

 

The dividing line between commercial and non commercial may become blurred.

 

KQED has no need for KCSM, so that path does not exist.

 

Are there shows that KCSM can show that KQED can not outbid KCSM? I have seen in the last few years KQED stopping KCSM showing some programs. Other stations trumped KCSM also.

 

 

 

 

 

 

The reason for creating KCSM TV has gone away, the delivery of teaching. I watched 3-4 series at least twice.

FCC rules do not permit one entity from owning more than 2 TV stations in the same market. KQED already owns two (KQEH is the second) so they cannot purchase KRCB. They're allowed to own KQET because it is in a different market.

I'm not expecting to see a lot of major changes with the upcoming auction but KCSM could be an exception. I think the FCC needs to relax some of the rules for non-commercial stations. It doesn't make any sense to me that a non-commercial station and a commercial station can't share the same transmitter in the DTV age.

post #8958 of 10422
I think there is room for multiple public stations. Both KRCB and KCSM offer compelling programming that KQE* does not (specifically CreateTV and MHZNetwork). With the money I'm saving with OTA, I have no problem supporting multiple organizations.

KCSM sadly is no longer accepting memberships. Unbelievable - you can't throw money their way even if you want to!
post #8959 of 10422
I'm a newbie in OTA, so I appreciate any help in answering some of my basic questions.

I'm in Mountain View, and simply trying to get a basic setup working to receive the major local channels (ABC, NBC, CBS, FOX). I'm renting, so I can't really install an external antenna or anything like that. According to TV Fool, I'm about 30 miles out from most of the signals, is there any hope for me with an indoor antenna? If so, which one should I try?

Thanks!
post #8960 of 10422
For decent reception, you really need an outdoor antenna, or one in your attic, for the stations on Sutro Tower and Mt. San Bruno.

I'm not familiar with most of the indoor antennas, but check out the indoor antennas on the Solid Signal site - http://www.solidsignal.com/ under "TV Antennas and Supplies". They generally give the specifications and tell how good the antenna coverage is in miles from the transmitter site.

If you can't find an antenna that will receive the stations from Sutro Tower and Mt. San Bruno, you'll at least be able to get the ones that transmit from the hills above Fremont. Fox 2, ABC 7, PBS 54, Univision 14 and Telemundo 48 have transmitters there, along with an independent channel 1.

Good luck!

Edit: P.S. I forgot KICU 36 that also transmits from the hills above Fremont.

No, do not use an indoor antenna, and here's why.....Simply walking around indoors will cause problems. (Like cell phone dropped calls) dropped digital tv signals or "pixelation" will drive you crazy.
Also todays indoor antennas are cheaply made imports. It will topple over and break when the cat walks by. They also have a useless 3 foot low-quality non-replaceable cable attached to them.... Who wants that ?
You can build one yourself that works better. Ask google, and when done, it would look similar to the channel master 4228
A metal- element Outdoor antenna is required. Outdoors,... in the attic,.... or under a king size bed. With industry standard RG-6 cable.

If TV Fool shows any of the stations you want are green signal levels, you have a chance with an indoor antenna. Perhaps the most important question would be, do you have a window that faces north?
post #8963 of 10422
I actually don't have a window facing north. The exact opposite actually, my place faces south and east frown.gif

Does that mean I don't have a chance with an indoor antenna?
post #8964 of 10422
Thanks for the suggestion. With an outdoor antenna though, how do you manage the coaxial cables? Wouldn't they be running all over the place?
post #8965 of 10422
I ran the coax through the ceiling and down inside the walls. I've also run them under carpet padding.

I'm in Mountain View with a good outdoor antenna setup (CM 4228 and amplifier), and I still have trouble with some channels. Though I have a problem with trees in the way, without them things would be easier.

The only way to find out is to try. Search "uhf replacement antenna" on Ebay. They still have the single classic bowtie available there. That's what I would start with. This bowtie is as good as antennas that cost 10X more, like the Silver Sensor, Leaf, and HDBlade. If KGO and KNTV are strong enough, it can receive those as well.

Another newbie here staying near San Jose Intl Airport. This is my TVFool report. I'm staying in a rented apartment, so mounting on the roof is not an option.

http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3dcc49e1d61fa6ca

I have Samsung UN40EH5300 TV. Do I need anything else other than the antenna to receive OTA channels?

I'm looking at these indoor antennas on Amazon. Any feedback on these?

post #8968 of 10422
You certainly don't have a signal strength problem. wink.gif I wouldn't buy an antenna with a preamp in your situation.

You will almost certainly have a multipath problem with an indoor antenna. A north facing window would be a good place to locate the antenna or even better any north facing outdoor space under your control, i.e. a porch or balcony.

No one can say with certainty which if any antenna will work. The most likely situation will be some stations will come in fine, others won't come in or you'll need to move the antenna to different locations for different stations.

Some high quality type models like...... Antennas direct DB2e or .... channel master 4220 (2 bay) are reasonable sized for indoor use. (About the size of a large shoe box)

Antennas Direct claims a peak gain of 9.85 db for the DB2e and a front to back ratio of 15.85 for that model. I never found a UHF indoor antenna that surpasses the performance of the basic 2 bay model.
Simply purchase 20 feet of coax, and mounting materials, felt base or wood stand. Hooks for hanging from ceiling, etc.

The terk you listed above is top heavy and can tip over easily. But it works ok.
The paper thin leaf has aluminum foil type of metal (bowtie shaped) embedded in credit card type of colored plastic.
Performance is somewhat compromised for that modern indoor fashion design.....smooth Black plastic.
Winegard scatter plane indoor antenna is a model to consider if you go that route. It has a removeable metal reflector and may be sized for the high VHF band .... an important feature you want.

Make sure you understand channel scanning. And the new digital tv VHF-UHF broadcast channel assignment channel numbers. (Listed on tv-fool)
Simply plugging it in.... doesn't work.... (DTV nightlight video) on youtube.
Good Luck

The Leaf is pretty good. It has a 6 foot cable already attached. There is also the HD Blade available at Amazon. It doesn't have a cable attached. Amazon offers this one with a good variety of cable lengths. The HD Blade is texturally like an over sized computer mouse pad. It's floppy when moved. This can be fixed. The Leaf is like a laminated piece of paper. It's firmer. Terk also offers the HDTVi which isn't amplified if you want to look into that one. The rabbit ears might help, or they might hurt. It's impossible to tell.

I'd check your Samsung and find out where the antenna input is. Then, figure out how much cable is necessary for the antenna to reach a location with a window. This will determine how much cable you will need between the antenna and the television. If you will need additional cable, something like this will be needed: http://www.amazon.com/GE-23203-Extension-Adaptor-Connects/dp/B00061UISM/ref=pd_sim_e_1

When you do hook up the antenna, you won't be able to simply push 2 on the remote in order to receive KTVU, you'll have to do a channel scan first. The Samsung manual will have those instructions. Prior to doing the channel scan, I'd tune the Samsung to a channel higher than 7. The stronger KGO repeater may scan in first.
