Will the pictured proposed method for mounting the GH10 1/4-inch reflectors perform electrically or not? I have been working on ways to mount 1/4-inch copper tubing reflector rods for GH10. The method pictured puts the rod inside 1/2-inch CPVC, with split PEX as a spacer, the ends of the metal rod crimped to space it off the plastic along its length. I know that having the plastic surrounding the metal rod will modify its effectiveness in the performance of the antenna. Would it be disastrous? Is there an estimate of how much the antanna's performance would be affected? Could the presence of the plastic be compensated for by changing the spacing of the elements? I have worked out a way to keep the copper tubing from migrating lengthwise within the PEX and the PEX from migrating lengthwise within the CPVC. The PEX could fill the entire length of the CPVC pipe, or it could consist of just short pieces at two or three spots along the length of each rod. Otherwise, if it would help the antenna perform better, I believe I could eliminate the PEX spacers and suspend the tubing inside the CPVC by other means. It seems to me that this easy method would make the reflectors streamlined and weather-resistant, though it could make the antenna weigh more and have more wind resistance than using bare metal rods or tubes.
