What kind of antenna connector is this?

I can't tell for sure without better pictures, but that looks like, not an RF connector per se, but a 3/8"-24 stud. This is very common for CB antennas. The reason I say it is not an RF connector is ...

How can I check if my CB radio is AM or AM/SSB?

As mentioned in another answer, it sounds like it’s not SSB. The next question is whether it’s AM or FM. “CB” can mean different things in different countries, and you don’t say which country you are ...

SDR CB Transmission

CB is licensed by rule (like FRS), and CB transmitters must be certified by the FCC (also like FRS). If the SDR you're using doesn't have an identifying label on it, you're probably not allowed to ...

CB v Amateur Radio

None of the above. There are no "73 codes" like 10-codes, 73 is just 73. Yes, I know about the 92 code, but it's well and truly dead, with no survivors other than 73 and occasionally 88, so ...

How can I check if my CB radio is AM or AM/SSB?

Australia has two CB bands, the old 27MHz band, where radios were either AM or SSB, & the UHF one, which uses FM.(which is apparently, the one you have.) Other countries have variations in either ...

Utilising old CB Base Antena to 5g Antena

A CB antenna will be designed for a frequency range around 27 MHz, much lower and also narrower than the bands used by 5G (multiple from 700 MHz to 6 GHz). It might work better than nothing, but to ...

Can I use my CB mobile antenna with a 10 meter radio also?

The same antenna won't be optimized for CB (~11 meter) and 10 meter ham bands at the same time, though that one appears to be tunable so could likely be used in either band. There are other ...

Performance of 2M/440 Amateur magnet mount antenna with CB
