Ignacy,
Thanks for the link to the rylwy.com information. I used the GagaParts 34
ft fiberglass pole with a 12 ft extension to support a 160M Inverted-V with
FCP during the past CQWW160SSB contest from a portable beach location on
the NC coast. Due to the beach winds, I used two levels of guying. I have
now obtained the lighter 34 and 50 ft carbon fiber poles and plan to use
them to support portable verticals and dipoles in future contests from the
beach site. I also have 17 ft carbon fiber extensions for both poles.
73,
Henry - K4TMC
