Very interesting! How about a AT4K tuner by Palstar in the shack to tune the antenna?

If you run any power at all, forget the balun unless you gat some sort of monster one, the usual suspects wont work for even moderate power AM.Any time I tried traps or baluns on AM, all I got was a fire.Some might take 50 watts carrier, but the DX100 blew out many a trap back when I was starting out in AM.BrettN2DTS----- Original Message -----Sent: Sunday, January 11, 2009 11:28 PMSubject: [AMRadio] 160 meter antennaI always wanted to try am on 160 but like most do not have enough room for a full size antenna, so,I am considering building a 160 meter antenna at our clubhouse because there is a 80' tower there and over an acre of land to spread out a 1/2 wave dipole. Question is;1 Is a 1/2 wave wire dipole the best antenna for the band considering there is room for it.2 Is 80' high enough for the center of the inverted V?3 How high do the ends need to be off of the ground?4 Should I feed it with coax or ladder line to the 10' level (or other) then a balun to coax to the tuner (coax is the only acceptable line into the shack)? The shack is a metal building 30X60' and directly below the tower. There is no way to get ladder line to the operating position since all cables have to run through a 3" conduit for at least 30'.The tower is a free standing commercial tower made of 4 20' sections bolted together with a 2 meter and a 440mhz antenna at the top, all ham antennas.Thanks for any advice.
