There's no reason at all not to use a base antenna with your HT. Just use a 12" section of thinner coax as suggested by kb2vxa.Is there any reason I can not use a base antenna with a handheld (5 Watt)? My concern is that the design of a big base antenna would lose too much power?? If this makes no sense feel free to advise.
If you hit your goal, why the roof? New goal?Thanks againt oall that helped with this project. I'm halfway there, but now have a diamond x-30 installed in the attic via 20' of LMR400, and a short rg58 jumper. I'm now able to hit a key repeater that was impossible before, which was my goal.
Next plan is to get my friend on the roof to install the antenna there.
