Seeking advice on initial setup.

If you use the mirror/bird perch mount, be sure and remove the stock antenna behind it on the side of the sleeper. It will interfere with the bird perch mount antenna and make the SWR higher.

 

It will work with the right side one only. Don't expect much from the AM band out of these trucks....at least none of ours work worth a hoot, even the 2015s.

 

I just installed a Galaxy 95t into a Cascadia for my son, it has a bar on the rear of the cab that I mounted the 90 degree angle antenna mount to.

I ran Times Mirror RG213u from the rear of the radio down the right windshield post under the door kickplate and cabinets in the rear and out an exsisting rubber plug in the floor, up the exhaust brace, leaving a drip loop between the antenna mount and the bar where I wire tied it.

I installed the short mount on the Monkey Made Antenna tuned easily to 1.1 to 1.
Dead Key 10 watts audio swing to just over 100 according to my Bird 43 meter.

Added a Motorola tin car speaker and a Roadking 56 mic.

Left the stock antennas alone, as well as the cobra 29 in the factory mount. I did disconnect the antenna cable at the Cobra and installed a shorting pulg on the Cobra radio to prevent the Galaxy from smoking it.

Radio works load and proud, I used a simular setup when I drove a Cascadia only using the mirror bolt extension, still did not remove the factory antennas SWR was about 1.5 to 1 I believe.

 

No not if the install is clean, better than messing around with mirror bolts, bad factory conectors, leaves the factory stuff in tact and your will work great, a 5.5 francis works well there also. I used the Monkey Made because we are HAMS and run wide in the freq band.
