Bruce's bucket trick is a neat idea.
I have a similar but different technique that also works great when working
I purchased a nice el cheapo fishing reel (the enclosed type, mine is a zebco,
forgot the model # (202?), I think it's even stainless steel, and it was $9.99
or maybe $14.99, can't remember). Instead of mounting it to a fishing pole, I
mounted it to the top of a 3 foot ground rod using some electrical tape. Take
it to the launch site, and stick it into the ground such that the top of the
ground rod is pointed at the intended target. Voila, no assistant required!
I am using the factory fishing line, and it seems to work fine. I use a very
heavy duty (black) swivel at the end of the fishing line. I use a sturdy
arrow with a threaded tip, optionally paint the arrow orange or orange/black
stripes for visibility, and screw in the heaviest blunt tip I can find. Then
wrap it with duct or electrical tape to further dull it, perhaps even adding a
few small pieces of lead shot, but keep it aerodynamically as smooth as
possible to help with aiming. (I like Bruce's BNC idea - might have to try
that. The more aerodynamically uniform, the better.)
On the drill press, I drill a hole the arrow just behind the feathers and tie a
piece of poly twine about a foot long in a loop through the hole. This makes
it very easy to attach to the swivel. I use a cheap recurve bow. Tried a
cheap compound bow, and even with partial pulls, the arrow was going up
probably 150' high, which was no good. And also, it was more apt to bend open
the swivel during launch if there was any resistance at all in the line. (Hey
Bruce, want to buy a nice compound bow?)
After getting the arrow over and down, either tie on the antenna support
string, or if that's too heavy to pull up with the monofilament, then first a
length of poly twine long enough to reach up and back down. Then use that to
hoist up the antenna support rope, or the pulley support rope if you are
working on the end that has the pulley. (WHAT? You are not using a pulley and
counterweight on one end of your tree-mounted dipole?!)
In 25 years of using this method, I have probably lost 3 arrows, and have even
installed antennas in 10 degree (F) weather (not that I recommend that!), so I
guess it works pretty well. And one stuck arrow even came down on its own a
few months later, fully intact. Note: The swivel is an optional item. If your
aim is great and you don't need a lot of retries, you may not need the swivel.
It just makes it easy to unclip the arrow, reel in the line, and clip the arrow
back on for a retry.
73 and happy hunting,
p.s. Remember that shooting arrows into the sky can be dangerous! Always
assume that the arrow could glance off a tree and go in an undesired direction.
And always assume that the arrow could become detached during launch, thus
flying the full possible distance up and then back down. An untethered arrow
launched upwards flies FAR!
Murphy's Law of untethered arrows states that if this scenario occurs, it will
most likely occur on the day that the neighbor leaves her brand new black
Mercedes out in her driveway, and that a most undesirable breeze will appear at
exactly the moment the arrow is release from the bowstring...
