ok so my cb antenna got cut some how under the heep. what my best way to fix it? should i get 2 pl-259 connectors and 1 female/female to connect them to. or should i just buy some coax with removable tip to feed it through the cab and tub? i've heard its not a good idea to cut and splice coax? but i don't know anything about cb's and optimal hookup options.
I'd suggest you just pickup a new piece of coax if you can.
It's possible to splice coax if you know what you're doing and it's also possible to do the M/F connectors like you mention, but all of those options will introduce additional loss on the line. It's likely easier and probably (depending on exactly what you have and buy) nearly cost neutral to just replace the whole run.
Its not the best thing to splice coax due to how sensitive CB's are. If done correctly it'll work. A lot of where the "bad idea" thing comes from is, its not THAT easy to splice Coax. Gotta be extra careful to not short the inner and outer lines.
I use my CB antenna as my am\fm antenna also, so i spliced the antenna into two relays so i can switch it back to the CB when i need to. It works great on both.
It wont have the ends you need on it but any piece of coax cable should work. If you have an extra one that used to go to the cable in your house or a VCR or so-on.
Or you can go by lowes or even walmart, anywhere that sells tvs. Otherwise its gonna be an online order or a run to the nearest truck stop lol.
Do not use television cable coax for your cb. It is 75 ohm impedence and you need 50 ohm impedence. Any good two way shop should have what you need. Especially a commercial radio shop such as one affiliated with Motorola.
You could splice it by installing a female PL-259 and a male PL-259 but as stated before, it will introduce additional line loss.
