Re: [AMRadio] Seeking advice on "wires in trees"
I have used a pulley system myself and have had good luck with it. But I used a boat winch to hoist the antenna up and down. I attached the winch at the bottom of the tree with a piece of wood block. The winch has locking teeth to keep it taught, and I detach the handle to keep anyone from playing with it. I used bungee cords at each end to allow some movement in high winds. I am now trying to put up a loop and am going to try electric fence anchors in the trees. Dave K9UX - Original Message - From: "D.

Re: [AMRadio] Seeking advice on "wires in trees"
The johnny ball idea is a very good idea, but if you use a pulley, go to a marine supply house and get one designed for sail boat rigging. They're expensive, but also bullet proof. They just work.

Re: [AMRadio] Seeking advice on "wires in trees"
Hi John, Bow and arrow have proven to be the best method for me in our woods. Metal arrow is drilled at the bowstring-end, and eventually tie a run of 20# monofilament fishing line. The leading tip of the arrow is removed and replaced with a fishing weight, which then is epoxied and heat-shrunk. Spray the arrow with day-glow marking paint. Compound bow can be cheap. Doesn't have to be a multi-pulley, expensive job. I use a 35# bow and have used the combination with the weighted arrow and monofilament to achieve dipole installations at 60-70 feet in height. I endorse the use of marine rope to minimize weather deterioration. I prefer to use pulleys at both ends of a dipole or one in the center of an inverted vee. This allows me to easily raise and lower to trim the antenna to frequency, and to occasionally inspect the coax, since that takes a lot of flex in a dipole configuration. Pick your branch, shoot your monofilament. Use that to then bring back your marine grade rope and pulley. The pulley should be a swivel type, marine grade or other weather-resistant, and the channel should match the size of rope. I use 3/8." Install a piece of old garden hose on the first five feet of the rope leading up to the pulley. This protects the tree. Now pull the pulley rope up to the branch, bounce the hose over the branch, and allow yourself about a foot or two lateral distance from the pulley to the branch. As it goes up, keep the other two lengths untangled as they all go up to that branch. One end of the service rope becomes your end insulator, the other is how you'll raise and lower the antenna on that side. Repeat for the other side. Center supported inverted vee is the same deal, one pulley, two ropes, but you tie off the unstressed ends of the antenna without needing a lot of load mitigation. The pulley rope, sheathed with garden hose, stays in place, while the second rope raises and lowers the vee for trimming, coax inspection, etc. Hope helpful. --Paul/VJB __ Our Main Website: http://www.amfone.net AMRadio mailing list Searchable Archives: http://www.mail-archive.com/amradio@mailman.qth.net/ List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Post: AMRadio@mailman.qth.net To unsubscribe, send an email to amradio-requ...@mailman.qth.net with the word unsubscribe in the message body.

Re: [AMRadio] Seeking advice on "wires in trees"
When you put the pulley up at the top of pine tree make sure it is a good quality one and test the uphaul line on it to make sure that everything is sized right and the line under load can't jam between the pulley sheave and the pulley housing. I've found that the antenna system if tethered high enough in the pine does not need springs or weights on the end of uphauls. The springiness in the top of the pine will take up the peak forces.

Re: [AMRadio] Seeking advice on "wires in trees"
Use twice as much rope. It's still cheaper than a climber and much safer. Get one rope up and over the high limb first. (Slingshot/fishing reel method or your choice. This one is to get the pulley up where it's needed.) Attach a pulley by its swivel to one end. Put second rope through pulley and hoist the whole mess up into the tree with the second rope dangling both ends down on the ground. Secure lower end of first rope so that it doesn't go anywhere. Attach one end of wire to second rope. Pull other end of second rope to hoist antenna wire. Tie everything off securely except the second rope which should be looped down in the shape of a "J" with a bucket of bricks suspended by a second pulley in the bottom of the "J". Attach the lower end of the "J" to a low branch and you have a compensated tension on your antenna that can accommodate winds and can be easily lowered for maintenance. Of course the other end of the antenna would be the same except for the weighted bucket would not be needed, just tie off the ropes. My version of this has been up three years and survived lots of storms. Too bad I can't draw a picture of this so I hope it's clear enough. 73 de Morris KI4IUA > -Original Message- > From: amradio-boun...@mailman.qth.net [mailto:amradio- > boun...@mailman.qth.net] On Behalf Of John, K5SEE > Sent: Tuesday, April 28, 2009 4:17 PM > To: n...@mailman.qth.net; amradio@mailman.qth.net > Subject: [AMRadio] Seeking advice on "wires in trees" > > I am going to need to have some tree work done before long.?

Re: [AMRadio] Seeking advice on "wires in trees"
John, Forget trying to cast a weight over a limb with a rod and reel. That combination is designed for distance, not height. It will take many tries to get a good placement, if you ever do. The combination of a wrist sling-shot and an spinning reel will do the trick far more easily and precisely. You can make one yourself, or buy one pre-made from one of the many ads in the various publications. I've placed over a half-dozen antennas this way in the past 18 months, and it's never taken me more than two shots per tree.

Re: [AMRadio] Seeking advice on "wires in trees"
Hi John, Are the bases of your trees located in dense undergrowth / bush...? If not, then read on... Procure a decent fishing pole / spincast reel (you probably already own one anyway, or know someone who does). Next, tie a good weight to the end of the line (I've used discarded automobile manual window crank handles with success --- they're about the right weight, & the chrome-finished ones are easy to find). Now, either you, or your fishing buddy, cast the weight up & over your "selected & ideal" tree limb. It'll doubtlessly take you a half dozen tries, or more, but that's OK. Once there, remove the weight, & tie some thin polypropylene packaging "twine" / utility rope to it, and start reeling the line in with the reel. Once across the tree limb & over to the other side of the tree that way, you are free to secure your final / permanent antenna support rope to the twine, pulling IT up over the limb now, by re-winding the utility rope. Presto! No need of any proverbial "...springs, pulleys, or rubber suction devices" whatsoever! Two final hints: (1) NEVER use polypropylene rope for the permanent support: the sun;'s UV rays will turn it to dust (literally) in about 2-3 years. Use NYLON / marine rope, instead. (2) If you're casting over underbrush, use a 9-volt battery taped to an old automobile warning buzzer as your weight: its buzzing drone will alert you as to its landing spot almost immediatetly in ANY thicket, & you'll save yourself LOTS of time, looking for cast lines, weights, etc. etc. Good luck! This is at LEAST half the fun of "raising" wire antennas, believe it, or not...! ~73~ Eddy VE3CUI - VE3XZ * - Original Message - From: "John, K5SEE" To: ; Sent: Tuesday, April 28, 2009 4:16 PM Subject: [AMRadio] Seeking advice on "wires in trees" > I am going to need to have some tree work done before long.?
