[TowerTalk] Tower and antenna decisions

[Pete Smith N4ZR]

My Yaesu Mark 5 would begin to roll back its power output over about 
1.8:1.  What really bugs me about LPDA's is the terrible tradeoff 
between weight and size and gain/directivity at any given frequency.

I swept my T-12 with my rig expert AA-230 analyzer and it was below 2-1  across the 13-30 mhz. range. Not sure what you are talking about, OR WHAT BRAND. But to say mediocre SWR is a false statement.
