My Hygain TH7’s on my tower were starting to fail after many years of service, it was time to replace with something new and modern. I contacted Radio Echo Communications (my personal tower crew) for a recommendation and they quickly sent me the GXP 16-3 specs. Ray mentioned his success rate with GXP's at all his RHR sites, under his suggestion I ordered two GXP 16-3 Tribanders. Its been over 18 months with these new antennas in the air, I’m quite impressed with performance with the stack @ 90/45 the bottom one fixed 45 degrees. The GXP 16-3 is on a round boom at about 34’ long with all stainless steel material and manufactured of the highest quality. These antennas have help up in ice, snow and a few nor’easter storms!. I break pileup's with ease, typically one call. These antennas have met or exceeded my expectations and are built of the highest professional level.
