[TowerTalk] 10M phased verticals

[Tim Duffy K3LR]

Hi John!

Currently the second stations (mult) only have access to the four square
receive arrays at K3LR. However, I expect to add run station access to the
four square arrays very soon. 

Yes, there are times that the four squares out perform the Yagi's. The
instant azimuth switching can be an advantage as well.

Are these phased verticals used exclusively for the multiplier station or 
does the run station also have access to them?  Are they ever better than a 
yagi for RX?

Hello Bill!

Three years ago I attempted to construct a proper four square phasing
network using four 5/8 wavelength elements and 1/4 wave spacing (on a side)
for 10 meters. I installed 60 ground radials - 5/8 wavelength long (60 per
element). I could never get acceptable pattern performance.

This last summer I converted the 5/8 wavelength elements to 1/4 wavelength
using a traditional four square phasing system. Performance is as expected
with 25 dB of F/B.

We use this antenna exclusively for receiving. The 10 meter four square
pattern is similar to a Yagi antenna mounted at 50 feet above the ground.
