Took my Gainmaster down about 4 months ago and replaced it with a Sirio Vector 4000. Vector worked great except screws kept falling out so I put the Gainmaster back up. Now I get swr's of 3 on all channels 1-40. When Gainmaster came down it had swr's of 1.2, now 3. I remeasured antenna 3 times, everything seems correct. I don't run power so I don't think I popped anything. Any ideas? Thank you, Harry.
