I'm installing a new vertical this weekend and am open to suggestions to get
more out of it. Here are the details and thanks:
12 meter tall self-supporting vertical built to take the highest recorded
wind here
Top Loaded with 80 uH, Q=300 coil
Four top hat spokes 7 feet long, no perimeter wires
Residential yard- antenna is 5 feet from the house
Radials running under the house for 30 to 50 feet
Radials in the yard running 35 to 45 feet to 1 meter ground rods
Fed directly with RG-8 (expect 25 +j0 at resonance)
Target radiation efficiency of 30%
The first use of this antenna will be running QRP in the ARRL 160 meter
'test.
