Re: [TowerTalk] Wilson 5 element 20 meter monobander

["Mark - AA6DX" <AA6DX@ARRL.NET>]

My Mosely used 46' --- it was a fire hose!   Compared very favorably to 
other mono bands and stacks in the area, both when I had it up in Washington 
D C area, and in Fairbanks.   Never used one nor had one I thought played 
better!   Would A/B with Rich, KL7RA and Lloyd, AL7CQ back in 1991 ... Loved 
that Mosely!
What a diff 6 feet make ... had a Wilson DB54 with 40 foot boom, just was 
not as hot ..  73, Mark ... AA6DX
