desktop radio wire antenna broken /what is best wire to buy to fix?

Thank you for reading my query. Pictured below is a memorex desktop radio with the wire broken off. To fix it, what would be the best wire to buy for the best reception. If fix requires soldering I will go to repair cafe. This is one wire I found on amazon but have no idea if it would work: <https://www.amazon.com/gp/product/B002FP...>

Hi @sue_59

Easiest option is to get a ~75cm length of insulated, multi stranded single wire, having approximately the same wire gauge as the wire remnant coming out of the radio and then strip about 5mm of the insulation from the end of the wire coming from the radio to expose the wire(s) and then do the same to the new length, tin the wires with solder, place a suitable length of heatshrink tubing over the new wire, solder the two wires together and then slide the heatshrink tubing over the joint to cover it, heat it until it shrinks and seals the joint.

A repair cafe should be able to do the repair. As long as the antenna is still connected in the radio then a join in the antenna cable shouldn't affect the signal strength too much

Thank you for taking the time to answer my question. This is very helpful to know before I go to repair cafe. I do not know how to get the same gauge wire or how to measure the gauge.

Usually judging by eye is good enough.

Most electronics parts stores have multi strand single wire available on a reel which you can buy by the length. Usually 1 metre or more

Strip back the insulation a bit from the antenna to see the wire as sometimes the thickness of the insulation can vary which is misleading as to the actual wire size.

These desktop/clock radios have simple (normally 1/4 wavelength centered on the FM band) antennae. The type of wire is not critical. As suggested a similar thickness multi-strand wire wil do fine. You don't even have to solder the connection - just expose the wire strands and twist them together (and tape the joint if you're fussy). What I have found (depending on the radio's sensitivity) is that the actual length is not as important as the it's orientation. If you live in an area with a strong FM signal then it hardly matters. If however the signal is not very strong you might want to experiment as to the wire's (antenna's) placement. I have a poor signal where I live and use an antenna wire that's meters in length. (Just extended the radio's antenna wire using the twist method).

If you listen to AM broadcasts as well, the radio will have a built-in (or sometimes a seperately wound external antenna which you can place for best reseption) directional antenna which is sensitive to how the radio is oriented wrt the broadcast signal - but once again only with a weak signal. (AM signals are usually stronger at night).

Thank you very much for taking the time to answer my question. there is a lot of excellent information in both answers. Thank you for the information about how I can do this without soldering. And also how the orientation is important. I was wondering if this wire would work--"Jensen 8309819 Universal Wire Antenna, Works with Any Stereo,<https://www.amazon.com/gp/product/B002FP...> It seems like I maybe could just plug it in ? Or would I just look up "multi-strand wire" at hardware store website/?
