If it drops down it's time to\nstart isolating parts of the antenna system using the same method.\n\nWatch your coaxial jumpers. Your connecters as previously noted, and one\nstab in the dark...check your power supply voltage to make sure you are\nmaintaining your 13.6 os so on transmit. RF into some power supplies drives\nthem funky.\n\nMaybe you can borrow a meter from a club member or just rebuild the whole\nshooting match. You already have all the parts. There is not much to those\nantennas so I would assume, if you have a problem it is coax or matching\nconnections related.\n\nRoger\nWA1KAT\n\n", "attachments": [] }
