Default Hacker VHF Herald RP37

I have one of these - a Freecycle find. It has a mains adapter inside that has been fitted in the distant past. It seems to work apart from a problem with the aerial. I'm not sure if it is jammed or what, but it won't extend with a careful tug with pliers. It seems to be well and truly seized.

Anyone know of a source for a replacement aerial, or how to unseize it?

Unfortunately, what you have there is just the mounting hub at the end of the aerial.
All the telescoping sections have broken off! You will need a replacement.
Sorry I don’t know of a source but I suspect other members will, and be able to give you the correct length if sourcing an alternative.

How long is the aerial in its unextended state? There may a 'U' shaped "catch" which the top end snaps into, or does it retract into the case?

From one of the letters to dealers that Nick kindly gave the Hacker group many moons ago, all available in the group's Photos section, the original aerial is 9mm. diameter, 190mm. long.

I've used these before on Hackers, several times - specifically in my case the Hunter model. There's no knuckle, and you'll need a replacement screw / cleat to attach the antenna wire. (Or just solder the wire direct)

Hmmn


For FM I've always found that the aerial needs to be angled at say 45 degrees to get good reception in a room setting.

Given its a Hacker and, the aerial is secured with a P clip, a Roberts R707 telescopic aerial would be my choice. It is well made, has both a knuckle joint and ball bearing horizontal lock and will match the quality of the radio you have.

Ask for one in the want's post.

Best of luck

Chris

Thanks all,
It was a bit optimistic hoping the aerial was just seized, the Roberts replacement sounds a good idea. I’ll check I haven’t got anything suitable in the garage before putting out a wanted request though.
