About 9 months ago, I built a 2-element quad antenna. It worked well until the plastic wire retainers on the ends of the spreader arms broke. I pulled down the antenna and made heavier retainers. 3 weeks later one of the bamboo spreader arms broke, so I hauled it down again. All of the bamboo spreaders were brittle and cracked even though I had given them several coats of spar varnish. So, I decided to redo the whole thing. 6 months have passed, and it's finally done.
The new quad has spreaders made from extruded aluminum tubing and fiberglas rod. Also, it's a direct feed, but I made a connection box so I can add a 1/4 wavelength of 75 ohm cable if it's necessary. I'm going to put it up on Monday. Hopefully this one will last a little longer.
