Not exactly electrical

Leaves carry moisture and become good VHF reflectors and absorbers. So avoid leaves where possible.

Hand hold your antenna on the ground or roof while looking at the Rx signal bars for each channel. I can get Buffalo from Toronto which much further than yours. Cable quality of RG6 is important and possible an antenna Amp may help if you have lossy long cable. compare your signals with TVfools.c om

Hello, and your question is very much "electrical" from an electromagnetic wave propagation question. I don't think trees generally have a significant effect on wave attenuation in the broadcast TV frequency bands. There might be some reflection if said trees are soaked with water during a rainstorm or have some metallic objects attached but otherwise I'd look for some other reason like the feed cable length/loss and the connections from the antenna to the receiver. A preamp will only be effective if the receiver itself is contributing significant excess noise relative to the received signal level. Also if you use a preamp it should be ideally located at the antenna feedpoint, not at the end of the feed cable connected to the receiver's antenna input. Sincerely,

Thanks all. I will look at the transmission line again. I am using the RG-6 Dish gave me so I assume it is pretty good wire. There are 2 and I have swapped them. The amp is at the antenna end. It is working because without it the problem is worse. I have noticed the receiver in the TV itself is better than the TiVo and for that matter two different RF modules in a Dish box. I am still longing for the days that a bad signal just gave you a little snow. ;-)

If you are trying to get an HDTV signal, you need a digital receiver and they usually are either full, clean signal, or dropped with zero screen output. There are no "snowy channels".

If you are still trying to tune an old analog TV station... there are not supposed to be any operating any more.

So UHF is all you need because that is all that gets broadcasted on any more.

Pretty sure there are no VHF broadcasters any more. Might have a tough time tuning a signal that does not exist.

I guess someone should tell our CBS affiliate to shut down then. He is on channel 11. (Digital)

ALL "(digital) "channels" *may* have a low banner number, but the actual assigned and broadcast frequencies are all up in the old UHF band.

All of them in the US AFAIUI.

A whole lot of stations needed to erect special new antennas for HDTV broadcast. A lot quit broadcasting. Most retain their old numeric though, even though they physically shift up into the UHF band.

In fact , I think those lower frequencies are being sold off for other, modern use now.

It is called "Spectrum Reallocation". Started in 2008.

If there are still VHF broadcasters that actually broadcast at those low frequencies today? I do not know of them as they all had to switch to digital, and I think it also required the band shift as well. Many keep the same numeric assignment number though.
