Will pay for itself in tower climber fees Time Owned: more than 12 months.
Outstanding final option for our 7000' ASL tower site. We tried fiberglass Hammo sticks repeatedly and they all failed after a year or two. So much for saving a couple bucks when we would have to pay for tower climber each time to swap out. This antenna is HUGE and comes truck freight strapped to 3 pallets. We ordered through Tessco in LA, they drop shipped from Sinclair in Canada. We though VSWR was a bit high at 1.3 when we first hooked up our UHF repeater - oops - had the leads mixed up and was on the VHF dipoles! Swapped cables and managed 1.00:1 across both ham bands on the respective arrays. This is a great medium gain antenna for sites where you're limited on the number of antennas (we were top mounted without space for a second stick) and have elevation. A lot of the local hams have gone with 4 or 8 dipoles or SuperStationmaster style high gain antennas only for the radiation pattern just to shoot over the intended coverage area. Higher gain=narrower pancake radiation pattern!
