Pretty simple. NMO base station kit secured to a PVC pipe. PVC is held b/w the bolt bolts by weight and gravity. It can easily be removed for antenna modification or complete removal. This is mounted in the attic. Antenna is TRAM dual-band(144/440) connected to a 996t. I was using the Larsen Special(150/450/800). I tried the TRAM dual-band for ****s and giggles. It improved my reception greatly, especially on 460mhz. Reception for repeaters/base stations is 35 miles and mobiles vary from 10-20 miles.
