Radio antenna socket

(1/3) > >>

davelectronic:
Recently picked up a DAB radio, portable Robert's retro RD-37. It has a telescopic antenna which is in good condition. I would like to fit a chassis socket of some type to allow connection of an outdoor antenna. Firstly would this be possible,  and would I need to add an isolation switch to disconnect the internal telescopic antenna. Kind of like a selection switch, I'm looking for thoughts as its digital, I've done it on an analogue radio receiver and that worked ok.
Thoughts and ideas appreciated. Also if possible, chassis socket type to use, N type F type etc.
Thanks for reading.

It wasn't click bait, I really wandered if adding an external chassis socket for an outside antenna might upset the signal on the telescopic antenna. Mainly as its digital signal.
Go it alone taste it and see.

Shouldn't be a problem, I'd probably use a premade pigtail and test first before I drilled the case though.

Benta:
You can call it digital, if you like, but the radio part is all analog and has the same demands as, eg, FM reception.

Richard Crowley:
RF is RF. There is no "digital" or "analog".

The typical solution is to use a plug-in telescopic antenna.  So you plug in the telescopic antenna when you want to use that, but then you unplug it when you want to connect an external antenna.  That way there is no fiddly switching of the RF signal.

Plug-in telescopic antennas are available in a variety of lengths and with various connectors ranging from PL-259 ("UHF") to BNC to RCA  and even 3.5mm.

The choice of exactly which connector to use is a matter of available space and aesthetics.  Only you can identify the appropriate options.  You can install the connector in the same hole where the existing telescoping antenna is.  Of course, if you want to ADD another connector and switch, then you must identify where you can put them without destroying the appearance of the gadget.
