Thank you for answering my question.
I have had the 4BTV for years. Good for receiving the amateur bands, and will use to xmt after I take my general this month. It was a real PIA to dismantle and move. I was just asking about the AT, which I do not own. A friend offered a used one to me for some favors that I afforded him at one time in the past. I am not trying to do eighty meters on the 4BTV, just up to forty. As far as radials, I am just now finishing the lightning radial (buried) system, and will next be installing the ground plain radials (stapled on top of the ground). There will be 120 of those about 35 feet long. I bit the bullet and bought the wire and bare crimp lugs that I will also silver solder. I go slow on my antenna projects as I have limited energy levels.
As far as real estate, I live in the outback. If you checked the FCC database, it is out date, I have moved; I no longer live in Gladstone MO; and they haven't updated my new address. I have acres to play antenna with for the first time in my life. Next antenna will be a beverage along the back property line... only six foot high, easy to work on, but long. As far as reading about antenna theory, I am doing as much as that as I can. Very few articles on phased verticals in QST (I think I have them all). I am no antenna expert, that is why I ask a lot of questions. The 4BTV will be the first up (other than my random wire that I have already installed) as I already have the mounting pole in the ground along with the afore mentioned lightning radials; next will be the Beverage late this year when allergies are low and the neighbor's horses are away for the winter. (I don't want to scare them with the auger, they are nice animals.) After that, it is a toss of a coin... either a homebrewed W2FMI short forty meter vertical with huge capacity hat, or a triangular phased array (homebrewed again). Depends on funds, how far away I want to put it, price of coax, my energy level, whether or not the tractor is running, etc & etc. My XYL actually encourages my radio activity, and doesn't mind the antennas, electromechanical Teletypes in the guest room, nor the 1A2 phone system that I have run throughout the entire house, complete with the 16 button Call Director in the QTH and the overhead PA. (Best phone system in the world, bar none!)
I doubt that I will ever work 160 meters as that requires truly large antennas. I do not
want any towers on my property, they scare me. Just relatively short (quarter wavelength), light verticals or wires. As far as burning through lots of money, aside from the 4BTV and accessories that I purchased years ago, most everything else antenna wise is built from found parts, eBay finds, scrap yards, etc (wire not withstanding) and small farm store purchases. (My VHF /UHF antennas look like an insane plumber with a torch and copper fittings built them...
Thank you again for the response!
