Admin please disregard if not allowed.
I have (2) Decibel Products Collinear repeater antennas. One is an 8 element with 12 db gain and the other is a 4 element with 9 db gain.
They both measure 1:1 swr, or very close to it at 462.500
I unstacked the top sections and they will measure around 442.000 individually at less than 1:5 swr. They can be modified for UHF Ham by extending the elements with a bolt, or at least that's what I've been told. That would have to be done to use the stacked (2) sections together in the UHF ham band. The best use is GMRS.
They are rated for winds over 100 mph.
$400 each. Located near Tyler, Texas.
