Cut away heat shrink from antenna?

Is it OK to cut away this part, where the heat shrink is empty?

Hi knave88 welcome to the forum! No you can not cut away that part of the heat shrink. It is actually not empty, there is a small exposed conductor in there that is the antenna itself.

Yep. The larger bit just below the tip is a crimp coupling between the flexy copper, and the active antenna wire.

Thanks a lot guys! So, I've almost made a big mistake

Here's what the DiPole antenna looks like under the heat shrink:

Update: there was actually about 3mm of extra heat shrink that I've cut!

Why did you need to cut it?

If you change the length of the signal wire, you're going to run into reception issues. Antennas have to have a specific length compared to the signal wavelength.

I've only cut the 3mm of empty heat shrink, the actual wire is in tact.

Wha'ts the big thing about cutting it? Is it going in side a shallow fuz or something?

Have you noticed any change when you cut the 3mm of empty heat shrink?
