Ok I have a few questions. I have two ground plane antennas that I'm trying to get in working order. The first one is an old hygain clr-2. I have built a new matching coil for it and after taking it down for the 15th time the lowest I've gotten the swr's was 2.7. Is there any easier way to do this? And the next antenna is the old super magnum m-117. And I dont know anything about it's matching coil or the overall length of the antenna. Any input would be great. Thanks.
