For that antenna, your proposed 4-5 feet of spacing with 1-1/4 inch mast seems fine, even for antenna 8 feet above roof. That is not a huge antenna like the HD8200U, CM-5020 or similar. One thing...

Sounds reasonable, but what antenna are you putting up, how high above the top-most bracket, and what is the construction of the mast (i.e. material, diameter, and wall thickness)? Is the mast all...

It depends on how high your mast is, antenna size, wind loads, etc. For a large antenna such as an HD8200U on an 8-foot mast, I would try to put at least 18" between braces, maybe more. That's kind...

Wow, that's some high-level analysis Tower Guy. It's neat that the recommended horizontal spacing is tailored to the precise channel, not just the band. Do you have a recommendation on the...

Good point. I missed that detail. It certainly does make it a lot harder. Seems worth a shot for a single antenna with good return policy though.

Based on the RabbitEars report, I think that CBFT and CBMT are certainly possible if you are up for a challenge. The are sitting at -5 dB noise margin. For comparison, I reliably (99%+ of time)...

That's a neat idea--- a repeater station with a Tablo and Wifi link powered by solar PV and batteries.

Tower Guy,
Why is the channel filter needed, i.e. why can't you just re-broadcast everything?

You need to put a repeater at the top of the ridge at the northern end of the pond. :-)

Unfortunately, I think even the Sherbrooke stations are took weak to pull in reliably, and Montreal looks even further down in the weeds. A Stellar Labs 30-2476 is your best bet to try for the...

Yes, comparisons across manufacturers can be difficult to obtain. Even when they do post gain vs. frequency charts, they can be on different bases (i.e. dBi vs. dBd) so you need to do a little math...

It looks like the southern end of the house has the best shot of seeing the RI towers. If the 751 doesn't work, a Winegard 7694 has a little more horsepower that might pull them in. There is also...

I can also recommend the Kitz-tech pre-amps. I have the KT-200 and it has been working fine for 3 years. Supposedly very low noise at 0.4 dB.

Would the KT-700 have lower noise than a "generic...

I think that was a good idea. Distance of 10-feet isn't very much, and if it makes it easier and safer to troubleshoot and service, it is worth the small penalty (fraction of a dB).

The voltage signal that the amplifier sees consists of "usable signal" (the part that the TV tuner needs to decode) and "noise". I think in broad terms, amplifiers increase both components equally,...

Mounting the preamp closer to the antenna cuts down on the signal loss, but I viewed the ~1.5dB of loss over 50-feet of down-tree coax as an equitable trade for easier access to the pre-amp. I...
