We've all searched for ways to support wire and other antennas from our towers. I've had varying degrees of success with wire antenna supports. I've tried wood, metal, and fiberglass. The most recent innovative use of "excess" parts was when I placed old "SteppIR" fiberglass tubes on the tower to hold up an inverted L for 160, and inverted V for 80 meters. It worked for a year, then the stress on the tubes - not intended for my application - became too much and they failed. My most recent venture was to acquire some military surplus fiberglass tubes, each 4 feet long, and 2 inches in diameter. The sidewall thickness is about 1/4 inch. They are very sturdy! I mounted the military surplus fiberglass tubes at the top of the tower with a 2-inch U-bolt and backing strip. I used a total of 5 tubes, for a total length of 20 feet. The pulleys for raising and lowering the wire antennas are mounted to smaller U-bolts with a caribiner to allow easy attachment. Once installed, the ropes make it wasy to work on the antennas by raising and lowering them. The extra distance from the tower helps reduce the impact the tower has on antenna performance. Emma, our Australian cattle dog, helps find the nuts and bolts I may have dropped during the course of the installation. Finished and up in the air, the newly installed military surplus fiberglass tubes are very strong, and up to the task of supporting the two wire antennas. If you need a source for these military surplus fiberglass tubes, I recommend you check on eBay. Good luck with your project - and let me know if you have any questions... 73, Joe, WDØM
