I haven't read all the responses to this original question. My suggestion is: put up a 1/4 wave vertical for the band of interest, but DO NOT put in an efficient radial system. Many have previously n

Lack of a good radial system only causes the low angle performance to suffer while typically not impacting the high angle performance as much. For "close in" stations - even NVIS - one is better serv

While that may be true for you on the left coast (the land of fruits and flakes), it is most certainly untrue for those in W3, W4, W8, W9 and W0. Most QSOs for those in flyover country are at takeoff

I've seen propagation studies that dispute that statement. However, that still argues for a height of roughly 50 feet for an 80/40 trapped or fan dipole (3/8 wave on 40 meters, 3/16 wave on 80 meters

Of course they do. Except at night in the middle of winter there is no "skip zone" on 80/40 meters. The presence or absence of the skip zone indicates that ability of the ionoshpere (density) to ref

No arguing with results, however, I would point out that your 400 mile radius will mean quite a different QSO count in a high-density amateur region such as W1 than in other areas. A 400-mile radius
