[CQ-Contest] TH7 Replacement

[Wayne Kline]

Scott,

I have a Skyhawk up last fall. Replacing a 5/5/5  20 meter stack..... Tower shrunk from 150' to  7er of Skyhawk's over the years.
I have installed a number   of triband antennas  all flavors of F-12's  Chushcraft A-3 and A-4's  and a few Mosley...

The Skyhawk IMO  was the  leader of the pack for both performance and mechanical  design.

I still have a 5/5/5 for 15 and  in fall of 16 the 6/6 for ten meters  and the Skyhawk  compared to them  did not win out ( it should not)and openings
But it performance was down most of the time by only 1 S unit..... Only on band openings  did the HP stack shine over the tri-band Skyhawk

The new JK antennas look interesting   also...... not 100% sure of there mechanical  survivability,, they look good !
