He is not testing an E/H antenna. He is testing a 90 ft tower and feedline, being the problem of common mode currents on the feedline are severe. I might add, he is testing a 90 ft tower fed in a less than optimum manner also...I could shunt feed a 90 ft tower like a normal person would, and beat his setup any day I bet. If I top loaded the tower with loading wires or a hat, Look out Mr. E/H ...It ain't gonna be pretty. I wouldn't have the lossy coil in the "E/H" apparatus to contend with for one thing. So I bet his test results of feeding the E/H ant-90 ft tower/feedline combo, most likely are inferior to feeding a 90 ft tower in a conventional manner, assuming equal ground losses. Note how the comparison B/C antenna compares overall... So lets see...The price ofa 90 ft tower plus wire for 120 radials, or a $40k+ E/H antenna plus the 90 ft tower as support. He says you don't really need radials...*snicker*...The E/H antenna setup will most likely be the poorer performer of the two setups. Dunno, I know which line I'll be in.. And I can tell you I won't have to drive to GA to pick it up...:/ MK -- http://web.wt.net/~nm5k |
