Don't let the name fool you, I know less than nothing...

My UHF aerial snapped off in some bushes. The aerial looks fine, but the screw bit is where it snapped. Am I able to replace just the black screw bit or does the whole unit need replacing?



Apologies for the large *.pdf files, forum wouldn't accept the *.heic or *.png image files..

Thanks very much.

Very much doubt you will get the part to repair it.

No, that’s rooted! For best performance get a new one.

Prestige Communications have a good selection here.

Thanks very much for the responses, everyone.

I’ll find the original receipt and look to replace like for like.

Cheers

I would find an aerial which has a light weight upper stainless top above the cylindrical section, instead of the solid unforgiving thicker one as pictured. The thin stainless usually have a centre open coil which adds flexibility. If replaced with same then same is what will happen.

We have a 150 diesel Prado and found that the fully metal ones wobbled a lot more than the fibreglass ones. When I broke ours I bought a cheap replacement at Repco in Alice Springs - it lasted about 5kms on a corrugated dirt road before it broke off! There are definitely a quality difference between a cheap no-name one and something more well known.

The top section of the aerial is detachable from what was the base. I suspect that that base section may contain a coil which is not physically connected to the lead. The wire protruding from the base excites the coil which is connected to the mast.

I suggest unscrew the mast and confirm the above. If correct, straighten the protruding wire and re-attach the the top section with a good adhesive (leave the mast off until set). You have nothing to loose.

That protruding wire IS connected/soldered to the threaded section onto which the top aerial is screwed onto. Just replacing it isn’t going to solder it again is it? ie, no electrical contact. If not connected the energy reflection on transmit will fry the output transistors. Have to be FANTASTIC glue to hold the mass and bending forces and impact forces the whole top section imposes on the coil mast. Won’t work.

For what it's worth and my 2 cents worth - I always carry a spare antenna whip in case of situations like this !

They aren't expensive and are easily stored without taking up any space !!


Happy safe and enjoyable travels
