Hello All, I can say that I feed my antenna on my Port-a-peater from the duplexers to the antenna with Beldon mil spec. RG-214/U it is silver and I use type "N" connectors on it, the duplexer is TX/RX and of Crosse the repeater is a Kenwood TKR 850 (non ver. two) it can be installed in about 10 minutes and will run all day. I forgot to add one thing I have a solar battery charger that just lays on the hood of my SUV to keep the battery up. The fold over mount is from Tar Heal antennas in NC and the 20' piece of pipe came from a scrap yard. The whole key is the fold over mount. The DB-404 I had from a early GMRS repeater site before I up graded to a DB-420. The above is my whole system and it works very well. We plan to use it in Riddley Creek PA on April 17 for one of the MS-Spring walks. Very best of 73, Russ, Ham, W3CH. GMRS, WPYK-254
