Question re. protecting base of wireless transmitter

Hi all

I have an idea to use Sugru (mouldable plastic which sets hard/flexible) around the base of some wireless transmitters (Sennheiser G5). I've always felt these areas were prone to damage. See attached image.

Any reason not to? Would this impact the signal in any way?

Thanks
Ben

Re: Question re. protecting base of wireless transmitter

As I stated elsewhere... I do not think it would compromise the RF any if used on the antenna base but I would not goop up an otherwise nice Tx case.
But I've never had any issues with antennas where they enter the case. The flexible part of antenna's usually get kinked up after a while, and if they actually break, they are cheap & easy to replace if your can DIY. (replacement antenna,Torx screwdriver, small soldering iron and about 10 minutes if you've done it before)

Might void any remaining warranty.

Re: Question re. protecting base of wireless transmitter

It is very doubtful that any kind of plastic or rubber material (like Sugru or equivalent) would have any significant effect on the RF performance of the antenna.

OTOH, those things are easy enough to disassemble. I have replaced broken wires by simply unsoldering them ad replacing with a new piece of wire. The type of wire is not significant. You could replace it with something stiffer and/or stronger.

However the LENGTH of the wire is CRITICAL to proper performance. So measure exactly from the body to the end of the wire and if you replace it, use a longer wire and then cut it back to the exact length after re-assembling the case.

As Mr. Palomaki suggested, it will void whatever warranty you might have. So you will ultimately have to make the tradeoff decision between patch / DIY replacement / or send it in for official $$$ repair.
