How to fix broken insulator on sennheiser antenna?
« on: July 19, 2021, 04:44:48 PM »

Part of the antenna insulator broke off a sennheiser EW100G2 body pack transmitter. Perhaps because I keep the antenna slightly bent when I store it.

The unit still works but I'd like to fix the missing insulation to prevent further damage. Any suggestion how?

I attached a photo.

Heat-shrink has worked for me in the past. However, the antenna wire eventually wore through.
The antenna itself isn't very difficult to replace as long as you have minimal soldering experience.

This seems to be pretty common on G2 TX antennas. Basically, you can use anything that you'd normally use for insulating wire (although in your case patching up the insulation is a bit tougher that close to the strain relief).

My go-to for the past several years has been H12-sized black Hellermann sleeves (possibly with an H15 added over top and halfway down the strain relief for addition anchoring). I'd be curious to see if liquid electrical tape would do the job, too, especially that close to the strain relief (I've never tried it).

I've used heat shrink as well. I built it up with a couple layers with the last layer
just large enough to go over part the strain relief.

Takes a set of tiny Torx drivers and a bit of bravery, but really it's not very difficult to do.  And the replacement antennas are surprisingly cheap.

In which case, order a replacement and a spare or two and done.  :)
