FM Rx antenna routing

A bit of a basic question here:

I'm routing an old FM Rx antenna wire outside the model, towards the tip of the stab (because routing to the top of the fin isn't practical due to a full chord rudder balance tab at the top of the vertical tail).

There's about a 6" length of antenna remaining beyond the attachment point - should I leave it dangling free in the wind or is it better to make a 90 degree turn and tension it towards a point on the fin L.E.?
(Avoided routing inside the fuselage due to having 3 metal pushrods there).

Leave it dangling un;ess there's a specific reason not to

In addition to PDR's comment it is not a good idea to fold it back on itself as this effectively shortens/detunes the antenna to some extent giving rise to a potential range issue.

I've (and others in my club) just leave it dangling because it won't harm anything.  :af

Well non-aggressive dangly bits tends to be a problem at your age. I gether they offer pills that can help.

But the OP was talking about antennas.
