post #5191 of 7642
On the recently installed 4 bay that I put up outside, the one where I couldn't use an amp, I noticed a marked improvement in the more marginal signals by replacing the coax with good old fashioned twin lead wire. (It's hard to find now)
post #5192 of 7642
There is less loss in twin lead, you just have to be careful running it near metal, and it is best if it is not touching things (raise it up by about 2 inches from stuff to help with attenuation)... You can still get it at Radio Shack...
post #5193 of 7642
From what I can see, a whole lot less attenuation. I had to jump it back to 75 ohm near the mythtv receiver since it doesn't have any 300 ohm inputs, but it's definitely a lot better. Where I had 25' of coax before, there is now about 3' or so. If you use twin lead you will want to "tin" the leads with some solder.

I thought twin lead wire was more subject to interference. So why is it they always recommend RG6 cable if twin lead indeed has less signal loss?

My experience is that twin lead is more satisfactory. as most antenna's termination is a balanced two ends, and twin lead carries the signal from that point better unless there is troubling stray electro-magnetic radiation present. Twin lead is a lot of trouble, but, better, in my mind..

I thought twin lead was completely outdated. I've never tried it on a modern TV and didn't think there was any market for it at all these days. And even if the signal is good with twin lead, wouldn't it be far more susceptable to the elements outside versus RG6?
post #5197 of 7642
At least where I am, I'm seeing no interference at all. I can understand where, for TV, a length of twin lead for VHF low could be subject to interference, but at UHF frequencies, I'd think it's not an issue for any length greater than a couple of feet. It's working so much better than the coax i had before, I think I will keep this arrangement for a while and see how it works out. I need to find a couple or three old school, screw in wall mounts for this cable.

Twin lead was the thing early in TV, as it was cheap and almost all receivers used 300 Ohm terminals. Then sets came with coax connectors to accommodate VHF , with a balun supplied, due to cable usage. Usually there were still twin lead screws for UHF. Then almost all sets came with a single coax connector. In between, shielded twin lead became somewhat popular. But, with TV sets no longer having 300 Ohm screw terminals, demand for twin lead went way down., even for antennas. So, in the market place, twin lead did become outdated. But, for UHF, I think it a bit better than coax. Better still, if TV receivers had 300 Ohm input terminals.

Being a ham radio operator, I know a bit about twinlead and coax. Twin-Lead is cheap and works great for long runs, and its' attenuation levels are much, much lower. Having said that, it is a pain to run - it shouldn't touch anything (keep it off the roof and ground, and where it enters the home) and you need to be careful around metal or it can become imbalanced (needs to be minimium about two to four inches away from gutters, etc.). It won't be destroyed, but if you break those two rules, its' benefits go way down. It is also harder to ground properly for lightning protection. The rise of coax is due to an abundance after WWII surplus, it is easier to run (it can touch anything), easier to ground for lightning, etc. However, the nice thing about twinlead is it is easily spliceable, cheap (if you can find it) and works fantastically.

I ended up getting some high quality twin lead (I keep wanting to call it twinax - from my IT days) off Amazon after not being able to find it stocked in any store around Huntersville. It wasn't exactly cheap given that 100' of it cost $25, but it's much heavier built than the twin lead that I remember back from the early 70s. It will probably last forever even exposed to the elements. As I said earlier, it's best to tin the stranded copper wire before you connect it up.

I'm thinking that if you ever wanted to delve into the tricky art of combining two antennas or adding a VHF dipole to a UHF antenna, twin lead is a much better way to connect them over using coax, matching xformers, and splitters.

Effective today (Oct 15) WAXN-TV1, China Grove will only air WAXN on 64.7. The programming in now in HD (720p). WSOC 9.7 is no longer available on the China Grove translator.

What is going on with RTV on WHKY? It keeps dropping, on and off, to a blank screen even though I'm not having any reception problems. The guide data is also wrong as it has been since the 1st of the month.

It would be good to find out else where besides this forum, maybe an e-mail to the city of Salisbury would be nice...smile.gif

Agreed that titles don't mean anything. It's why clerical worker is called vice president at big banks. No license required.

Well, if you had to cut one of the signals off the China Grove translator, WSOC was the logical one to let go. We know WSOC already has a much stronger signal out of NE Charlotte versus the signal in NE Charlotte for WAXN. Perhaps anyone that is in range to receive WSOC on 9-7 can already view WSOC on 9-1? But we know WAXN is much different. I believe you are required to protect WFMY on RF51 so I would imagine the signal on the main WAXN RF50 is never going to be that impressive. But your translator in China Grove for WAXN certainly helps to boost coverage. And no doubt there are a number of your viewers who rely on the China Grove site for dependable coverage of WAXN.

That is true, we have an issue with the quality of the WAXN Translator feed from China Grove and have to switch over to the Charlotte feed which is on the fringe for reception.

The translator at China Grove is licensed to WAXN.. so we can show WAXN and WSOC or just WAXN...we can not do WSOC only. We feel that the main 9.1 and 9.9 out of Statesville cover this area. Where the China Grove site covers the null in WAXN's main pattern due to protection to WFMY. It also makes WAXN HD now on 64.7.

That should provide a stronger HD signal for WAXN in Rowan County, where 9.1 is already available. So that sounds like a good decision.

We are keeping an eye on it and hopefully it will have good strong signal with no drop outs...smile.gif

I wonder if one of the Charlotte channels will consider picking up the new Cozi subchannel in January. It is a new retro channel from NBC. Perhaps WCNC or some other channel. I enjoy retro programming such as Antenna TV and MeTV. So far it looks like it will be seen in Raleigh since WNCN is an NBC O&O station.
post #5216 of 7642
WNCN hasn't been an O&O for years. They are owned by Media General.
post #5217 of 7642
I think there is still broadcast space in Charlotte for more channels to happen. WJZY has shown what can be done if a station is willing.

While we are on the subject, I'm starting to wonder if Soul of the South is going to get off the ground. I did a little looking for them on the Internet and can't find anything recent, and they seem to be 1/2 year or more past the date where they said they would be on the air, which was announced more than a year ago. I did also see an article where they are planning to use the Internet to distribute content to their affiliate stations rather than satellite feed. I'd wonder a bit about the relative reliability of that vs. satellite but maybe that's more common now than I thought it would be.

Cozi does have an interesting oldies line-up, including The Virginian, Kit Carson, Alias Smith and Jones, Marcus Welby, Highway to Heaven, Red Skelton, Charlie’s Angels, Six Million Dollar Man, Bionic Woman and Magnum P.I.

Hopefully, it will eventually break into the Charlotte market.

Also they will have the Lucy Show.

I had forgotten about that. So it should be offered to any station interested, not necessarily NBC affiliates.
