Plastic tubing around 2.4GHz antennas
I was at a regional turbine meeting the other day, with a pass to walk through the pit areas, so I could see the insides of many jets. I noticed that, in the vast majority of them, the antennas of the 2.4GHz receivers (all but one were JR) were fitted with a plastic tubing - apparently the same polypropylene tubing used in retract lines - around them, as if to keep the antennas always "more straight". What's up with that? Does it help? How? Would it be helpful in any type of plane/installation/2.4GHz system?
Thank you in advance.

Probably a good idea. Inotice on one of my 4 stroke models the little antenna wire oscillates in about a 1/4 inch circle at the tip. The tubing would dampen that motion I am sure.

. . . with 2.4 it helps to keep the small antennas safe as they are easily broken compared to the older longer antenna wire.
ANYTHING external is in peril of grass, sod and tree damage. And internal they still have been yanked out of the Rx when the fuselage seperates or a lead tail weight suddenly becomes a tank-clunk.

Sorry, this isn't a great picture, but you can kind of see it on the AR6200 in the attached pic.

Sgillmore's picture is exactly what I saw, only with what looked like polypropylene retract tubing instead. In like manner, that tubing was easily and stably fitted around the strain relief nipple of each antenna terminal.
Thank you for sharing the picture.

RE: Plastic tubing around 2.4GHz antennas
Hi Guys,I have been using the hitec 2.4 receivers,with no problems.
They have a barrel at the end of the antenna with a 1inch piece of small coax cable,extending beyond the barrel.
It is used to stick through a carbon fiber fuselage,which I don't have.I like to sleeve the barrel with a small piece of drinking straw to protect the coax cable.Works Great. Thanks Ed

Clear aquarium air line tubing for my Airtronics antennae cables ... works a treat. Cheaper than fuel line too
