 Gentleman,               Would increasing the boom length of a 2 ele. 5 band 
 quad from 8' to 12' be worthwhile? I'm thinking this would increase gain & 
f/b 
 curves. Just looking for that extra punch on 17 & 20 meters.               
 comments please John KB3EAY

    I've run a bunch of patterns and there is an advantage of having more 
than .125WL in spacing in gain and most F/B.  A friend insists he can tell 
the difference on the air.  It's better on the sides and back.  The vertical 
pattern is a bit sharper and will be beneficial.  I plan to use around 
.14-.15 WL as I got some real deep nulls in the rear over 50 dB.  To make use 
of it over the band you will need a variable Xc in the reflector driven by a 
selsyn at the mast.  k7gco.
