Comment on Wing Shack, I hardly knew ye by J. Wilson

Hey…I liked the fact that amateur local talent was featured on Sunday afternoons. I’m a teacher and some of my kids performed at the “Wing Shack”! Now, I’ve got a new crop of wanna’be’s but there’s nothing like the Wing S. where they can perform. Any suggestions would sure be appreciated. I run a guitar club and these kids need a place to get started!

Thanks. I’ll go and buy a preamp as you say, asap. I’ll let you know how it goes.

@Len Jeffrey Have you tried hooking *only* your highest-altitude 4-bay with a pre-amp to your TV? I think this would dramatically boost your signal. Sensuz carries the high gain pre-amp that works well for me (CM-7777). All the links are in the above post. I can't help you with the balun information, that goes beyond my understanding at the moment.

Thankyou for all of the information that you have given to me. It makes complete sense.I actually added another 4 bay antenna and got no new stations. I tried moving it in different directions while my wife was at the other end of a walkie talkie watching a level meter on our tv screen[not very scientific].
So that’s the way it stands right now. We only get channel 29 after midnight on clear nights but all other channels from the direction of the cn tower are strong all the time. What if I added an booster to one antenna aimed at channel 29. Would that weaken the other channels by roughly 50%?
Also, another thought. Why are the 4-bay,8-bay,etc. antennas terminated with 75 ohm connectors? Those antennas are 300 ohms??

@Len Jeffrey
I think you are doing yourself a disservice with your setup. Granted, I don’t know what you are going for, and I’m not an engineer, but here’s my thoughts anyways.

When you use a signal combiner like that, you are basically chopping your reception by half or more. Here’s why (as was explained to me):

Say you want a channel, 29 for example. If you aim one antenna directly at 29, and get 100% signal, that is great. Now say you want something off of the CN Tower, so you aim an antenna directly there, and you get 100% signal. Ooops, now you want to get both, and you combine them. Assuming that the antenna aimed at 29 get 0% signal from CN Tower, and vice-versa, yo will end up with 50% signal for both. That is a best case. You can also introduce interference if you have more than 0% signal, as the combined signals are likely out of phase.

How does your reception work with *a single* 4-bay antenna, and a pre-amp mounted at the top of your tower? I suspect with correct alignment you will get all of the channels available.

Anyways let us know how it goes!

Обалдеть!... In April I packaged up my source for the keylogger, and posted it to the project page. Just thought I’d mention in a post that it is now available.....

Great post! This really inspired me to take a look at our old telephone wiring. Everything is run on top of the electrical wiring… I ordered a dsl splitter yesterday and can’t wait to see the results.

I have the original, amplified round radio shack antenna at the top of the tower and three of the four-bay antennas connected in parallel into a 4 in/one out splitter box. Actually, the splitter box was meant to be used as a one in/four out tv box.This weekend I will be aiming the fourth antenna towards channel 29 and placing this antenna higher than the other two four-bay antennas. I have been receiving channel 29 whenever the weather is good and usually only in the mornings. I haven’t been able to spend much time in setting up the last antenna because of bad weather and having to go to work.I will see how this works out. What do you guys think?
