Got off my ass, grabbed a drink, headed out to the pole barn, and installed the Anyone AT-778UV dual band radio and the Tram 1181 dual band antenna. Have I told you how much I love RAM mount products?
For the antenna mount, I wasn't too concerned with a ground plane (will mostly use for GMRS, but I am a licensed ham), so I went with a cage mount. Someone in another thread recommended the Xaxia Alloys mount - it was a little spendy (damn near half the cost of the radio!), but very well constructed. I have the antenna roughly 4 inches above the roofline on the driver's side. If it gets hosed, not to worry, it's only about $30. Prolly switch to a Midland MXTA25 3Db gain Ghost antenna if that happens, or lower the mount and use a Midland MXTA26 6Db gain whip that I could hid under the roofline when heading into trees, garages, or enclosed trailers.
The missus and I tested the rig out with a Baofeng UV-5R on the other end and all was well. I do think I need to mount an external powered speaker, as I know the P1K5 will be pretty loud, but I'll figure that one out. Not sure where the mic will hang, so I have to figure that out as well.
