A pack of 5 plastic guy runners for aerial and tent rigging - These are not just for adjusting the tension of your support lines, but can be used as dipole insulators - you get a pair of these in our Dipole Centre Kit, too!
In the 2nd picture, you can see how useful they are when connecting 300-ohm balanced feeder through a ferrite to a short length of RG58 coax to your ATU. The holes are ideal for M4 fixings.
Although these are perfect on their own for simple /P Dipoles and lightweight home setups, for a stronger insulator, you could superglue 2 of them together or use these larger "Egg" insulators. The 3rd picture shows a comparison between these and the larger "egg" insulators.
Need some support line? We sell 2.5mm cord in 20m bundles and 50m reels.
