Purchasing Cobra 29 LX Digital need antenna recommendations please.

best location for any antenna will be high and on a flat surface like the top of cab
you said a solid mount then you stated a 4 or 5 foot fiberglass antenna would work
102 may be a bit long for you to run
so i would go with a puck mount and a 17 inch shaft Predator 10K
with that puck mounted just in front of the brakelight
with some lmr 240 coax
this setup may be a little extreme for what you want to do
but hey why not do it right the first time then go back and spend more money

 

I always hate to go below 5ft, 4.5 at the least, 5.5 is ideal, but I've seen some 4ft set ups that work pretty good. Good luck!

 

I have the fender mount on my Durango with a 2000 trucker and have the SWR's matched at 1.1:1 also, my father has the fender mount on his ram with a trucker 2000 with the same SWR's as me. We both ordered the ram kit from right channel radios, comes with mini-8 coax... just make sure the kit is for 04+ rams as the kit for 94-03 will not work on yours... HTH

 

Make sure you don't tighten that stud down to tight, them right angle stubs like that one are just pressed together and break easy. I recommend the fire ring setup
