[Antennas] Antennas in trees.

[Riichard Neuman]

I assume your slingshot has fishing monfilament.  Not sure what antenna you want up.  Once monofiliment is over branch you want, attach nylon twine (white #18 sold at Walmart) to the end of slingshot line and pull the the twine over the branch.  It is strong stuff.  Then attach the end of the wire to the end of the twine you want up and pull that back.  The wire (THHN #14) will end up over the branch.  The only problem I have had is a problem-child squirrel that chewed thru the antenna wire over the branch.  Wood is a pretty good insulator.  No problem even in rain and snow .  I run legal limit.  I have used this technique for years. Wind is the enemy as the tree sways in heavy wind.  Near ground level I often have a breakaway point on a corner support, etc. so if storm wind is gonna break something it won't be the antenna itself but a ground reachable support line  I've used these for many years.  I have a full wave 160 meter loop,  2 ele 80 meter phased loop array to EU, a single 80 meter delta loop SE/NW,  a 20 meter quad SE, a 40 meter Moxon SE.   Not something I read about, something I use.  Yes there is some maintenance but surprising not a lot.  I usually take a quick look at exciter power SWR before I put amp in line. 

73 and good luck,
Richard

P.S. A tennis ball launcher works best... better than slingshot, bow/arrow, etc

      I have a 90' tree I want to shoot an apex of an antenna into.  My
rig of a Zebco and slingshot work great.  But what do I use to haul the
center of the antenna up?  Not just something you read about, but have
used.  I'm Texas, so Sun is the major problem.

73, Ken
