I have a Roberts Blutune 50 which is generally in good working order, but all it has as an antenna is a piddly wee wire snaking out the back - I reckon it to be about .8mm or thereabouts. Unfortunately when moving the antenna snapped off at the back. I decided to open the unit up to check if I could extend the antenna, but I didn't really see what I expected from most guides and tutorials for fixing antenna.
All I have is that single wire (with not much length, since it broke off fairly close to the contact) and I can also see a very similar wire connected to either the same or a very close contact which is clipped to a metal panel on the back of the radio. I assumed this was something grounding, but perhaps it is relating to the signal?
The guides and tutorials I'm seeing all seem to reference multiple wire ends to extend and things like, that, but all I have is this single wire. What am I to do?
EDIT: for extra info.
I'm afraid I don't know how long the original antenna was - if I had to estimate, probably about 3-5 feet?
Here are a couple of images:
After a little more digging, I think my next step is to find a length of wire and attach it to the broken end. I'm not sure of the exact details of this (length, material or thickness of wire?) so any contrary or supplementary advice is appreciated.
(I also appreciate the meta-issue with this question, as pointed out in the comments, so am very grateful for any allowance for continued assistance.)
