Here in Ohio verticals don't do such a great job, poor soil, I have had many
vertical including the Hytower - I would recommend one of the mounted
verticals such as the Gap Titan or perhaps the Cushcraft R5 - the R5 is an
electrical 1/2 wave and does not require radials, the Gap is a 1/4 wave
vertical dipole, and also does not need radials...good luck..
