[Antennas] 5-Band Quad VSWR

Thu, 2 Jan 2003 13:57:54 -0000

Walter,
I wouldn't be satisfied either. 
I did a search and found several hams using the Lightning Bolt quad
http://www.eham.net/reviews/detail/423 I would contact them and see if
they had any insight

Dave,
Thanks anyway for the reply, but like I said in my original message, I
already have the tuner and am using it. However, knowing how excellent
the
bandwidth was with the 2-element quad in relation to the way it is now,
..."I will never be satisfied until the quad can be tuned for a better
VSWR."
