Put a bolt through the hole and secure. Be sure to silicone the hole good. Also be sure you have a wooden dowel rod inside the fiberglass mast, all the way across the boom for strength and support. The dowel rod should be siliconed in also. On the 440 antenna, build a small aluminum right angle bracket. Lay it against the side of the antenna and sheet metal screw it to the toothed u bold cradle. Also run a wood screw through the angle bracket to the boom. This should stop the windmilling. As far as gain with the circular polarity. DO NOT base anything on land based repeater sites or simplex contacts. These antennas won't perform as well as a good Diamond ground plane. However they are unsurpassed in space performance. The circular polarity costs gain locally but are the best with moving space objects. Hope this helps.
