Hi Richard,
As you would expect with a 4 1/2 foot boom and 12 foot elements, bandwidth
on 20 is not super. Mine is tuned for the SSB portion and I get less than
100 khz no tuner. I use the auto tuner to tweak it. To work CW or RTTY,
it's worth the effort to use the Palstar manual tuner to get it flat. I
think the model that also covers 12 and 17 meters has to give up more 20
bandwidth to acomplish this.
No change in SWR as it turns. I think you are right in suspecting close
proximity of the neighbors house as a reason for erratic swr as the beam
turns. While many antennas will see some change in swr in wet weather, it
is pronounced with this antenna and resonant freq will drop a bit in a
rain storm Maybe 100 khz on 20 meters.
Mine is only at 23 feet and all above info is likely to change if up
higher I'd of course prefer something bigger, but until then this suits
me. .
73, Steve KW3A
