Hello, Al:
The Winegard HD7084P antenna suggested by ADTech and Tower Guy is still the best for you, because you need WRGB on real channel 6.

You can see the networks available to your zip by clicking on the callsigns here:

And the aim is still 79 degrees true, 92 degrees magnetic by a pocket compass, not an iPhone compass. You can also use the green signal lines shown on the TVFOOL interactive map browser, after you move the cursor to the antenna location, to pick a landmark for aiming.

for example:
The "new" Channel Master 7777 is probably still the best preamp for you. It is easily overloaded by strong signals, but you don't have any. Based on an estimate of your location, I also don't see any strong FM signals that would interfere with the reception of channel 6. The 7777 has an internal FM filter that is set to IN by default, but I'm not certain if that will affect channel 6 or not. See attachment 2. You can do your own FMFOOL report here:

Alternate preamps are the CM 7778 with a little less gain but more resistance to overload, and the RCA TVPRAMP1R which is less expensive but has a history of quality control problems.

I will be purchasing and installing antenna in the next month and a half. I will be renting a lift to install a chimney on one side of the house and thought that would be a good time to install the antenna.
|
I understand your problem, but I don't think it's a good idea to mount an antenna on the chimney until the mortar has reached full strength. And I question the wisdom of mounting a large antenna on the chimney even after the mortar has reached full strength.

The install of the antenna for me will be a one shot deal as I will not be able to get on the roof with ladders I need the lift. and at the price of rentals I can only do this once.

Because of so many unknown factors, like the trees, there is no way I can guarantee immediate success; some experimentation might be required.
The coax shield should be grounded with a grounding block that is connected to the house electrical system ground with 10 gauge copper wire for electrical safety
and to reject interference. For further compliance with the electrical code (NEC), the mast should also be grounded in a similar manner to drain any buildup of static charge, but the system will not survive a direct strike.

The house is off-grid and the power system (Batteries and inverter system) is in garage and ground rods are in place.

Inverters can cause interference to TV reception. Sine wave inverters cause less interference than modified sine wave (which really should be called modified square wave) inverters. The interference can be conducted, radiated, or both. Some off-grid systems have a small sine wave inverter like the Exeltech XP125 for the TV and move the antenna away from the house as much as possible. (I read Home Power Magazine.)
