    Anyone familiar with lightning L6 quads? Problem matching?
  • @ BJ radionut:
    What's the issue with the Quad....the Lighting uses what I thought was squirrely dual Gamma Match set-up to get both polarities
  • @ Jim5570091:
    I have higher SWR on 40 2.25 channel 1 is 1.1. I had to change the matching stubs they was broken. I used the same diameter 316 stainless steel welding rod. Does the length of the matching stubs effect the tuning. I’m trying to figure out how to post some pictures of what I’ve done. Give me a minute.
  • @ Jim5570091:
    I posted a picture on a thread on Lightning L4 thread. Not sure why I’m having trouble posting it here.
  • @ BJ radionut:
    Length on matching stubs is critical...Length of rods is part of the overall antenna...Would appear antenna is too Long...same on Both Polarities or different?
  • @ Crawdad:
    Here's a thought: Could the length of the SS welding rod need to be different than what the broken rod(s) were due to a different Velocity Factor of SS?
  • @ Jim5570091:
    Close to the same. Thats the rout I was going. But needed a second opinion. Thanks cranking the hazer up and down testing was getting to an old man. Upper 90s here. Cheers 297 The red dog north Alabama.
  • @ Jim5570091:
    Maybe. I wasn’t impressed with just clamping the shield wire to the boom with a hose clamp. I built a l bracket with so239 female hubs. I posted a picture on the recent gallery’s.
  • @ Jim5570091:
    Well I cut the matching stubs down 1 inch at a time from about 20” down to 6”. Still no real changes.
  • @ 555 Central Missouri:
    Hello everyone, I have a old courier centurion pll 40 channel SSB, it has the extra channels and it has another switch that just moves the frequency down one channel on the dial, what is the purpose for this?
