I see from Southgate ARC news that Derek G4CQM is looking to publicise his antenna designs. He has done an update to his website with several new antenna designs. The designs are fairly simple to construct and all the details are available for free on the website. Lionel VE7BQH has provided performance analysis tables that show how well the antennas should work.
The only issue I have with Derek’s designs are that he insists on using Netlon clips to mount the elements. Netlon clips are designed to hold garden netting for climbing plants or shading. The problem is that the clips are held in place by a single bolt, which means that over time the elements move out of line and eventually spin like helicopter blades in the wind. Still as radio amateurs we tend to adapt other peoples designs rather than follow them to the letter so I don’t see it as too much of a problem, unless of course you buy one of Derek’s kits.
Edit: I was wrong about the Netlon clips. See Derek’s comment bellow
