[Antennas] 20m quad on 30m??

[Robert G Strickland]

Jan...

I ran a 3-band, 2-el quad for over ten years. I modified it several 
times from the original Lightning Bolt design [5-band, common feed] to 
the 3-B, 2-el, switched feeds final design. I ran the final version on 
30m frequently without any feed problems when using an outboard tuner. 
Hard for me to say what the pattern/gain looked like. However, it did 
show a frontal lobe, side nulls, and some f/b ratio. I could work 
whatever I heard without much trouble. By comparison, I subsequently put 
up a SkyHawk on the same tower, and it performed a bit better on 30m. 
For that matter, I occasionally used the SkyHawk on 40m with some 
success, also. Hope this helps.
