[Antennas] 5-Band Quad VSWR

Thu, 2 Jan 2003 09:14:06 -0500

Randy,
I checked out that page. Great source of quad users. I even saw my original
review and testimonial of my previous 2-element quad. I should have
completed the VSWR readings of the 4-element unit before I wrote that review
though. huh.
