Portable Antenna Halyard

At my home QTH I’ve always used halyards to haul a pulley up that in turn holds the antenna support rope. It takes more rope to do it this way but it works much better than using a single rope. Recently I’ve been using my  LNR EFT-10/20/40 Trail-Friendly antenna a bit. There are two downsides to placing it well up in a tree, 1) it is made of very thin wire which is great for portability but I’m not really excited about using the antenna wire to haul it down because, 2) it has a built in winder\choke which again, is great for function and portability, but unfortunately the winder\choke doubles as a limb catcher. The solution to this problem is to use the throw line as a halyard, not the antenna wire. This actually allows you to have much better control while hoisting the antenna, and the throw line acts as the downhaul instead of the antenna wire. If the antenna does get snagged you can use the throw line instead of the antenna wire to work out the snag.

In the picture the blue box is the end of the antenna tied to the throw line with a bowline and the red box is the winder\choke. Using this method I can easily maneuver the antenna wire through tree limbs and overcome snags using the much stronger throw line as opposed to the antenna wire.
