I am in process of installing Two Verticals with a Dunestar
Phasing box for use on 30 meters. Literature on elevated
Verticals/Radials not vast (what I can find) but off we went.
Using the railing on the back deck (6 feet above ground) for
support. Antennas are 1/4 wave verticals with 4 1/4 wave radials.
Now for interesting part: SW vertical (about 18 inches from wood
side of house) works fine, SWR less than 1.5:1 using MFJ-259
SWR analyzer. NE vertical, out in open, works strange. Resonant
frequency around 8.5 MHz, adjusting antenna length has little
effect, both antennas and radials identical. Now for speculation;
Antenna mounted on deck rail, which is pressure treated wood, can
that introduce strange effect ? changed coax, no change, so now I
am stumped. Any suggestions ?? Tnx, Dick, W1KSZ
