I have 4 power antennas. 3 of them need new masts/nylon wire rebuilds which can be done for about $40 each. One of them already has a new mast and nylon wire in it and was working perfect until just now. I'm done dicking around with them. You can buy them, rebuild them sell each for a nice profit. 3 of the motors work in them. You get all 4 of t hem for $150 plus shipping.
