Here is my dilemma. One of my current work radio sites is being decommissioned and torn down. My new replacement site has some antenna restrictions and I'm having trouble finding an antenna to fit the bill. The old site is 110 ft. tall and I have a DB-264 antenna set for omni pattern at 6 dbd on the top now. The new site is 225 ft. tall but will not allow dipole antennas only fiberglass collinear antennas. I normally use the Sinclair SC229 in this situation, but the site management says that is too tall and doesn't want that either. They will only allow something up to 16 feet in hieght, give or take a little. So I'm looking for something of high quality commercial grade and about maybe 3 to 4 dbd gain, around 16 ft. tall or so. I thought that there were these type antennas available as I've seen and used them before, but now I can't seem to find anyone that sells new ones. All I can find are unity gain or the big ones like I already have. Did the main antenna manufacturers stop making the in between size VHF collineer antennas? If I'm just missing it for some reason, or losing my mind, can someone point me in the right direction.
Thanks
