Keeping things simple (and lightweight), this 3rd-generation of our popular dipole/doublet centre is great for portable operating or even for use at the home QTH. New larger size with additional holes for strain-relief plus the direct feeder connection allows you to mount it high up a telescopic fishing-pole without the extra weight of connectors. Their bright-yellow colour makes them easy to find if dropped in long grass.
These are precision laser-cut so for extra strength you could glue 2 together if you really wanted - you can select "Centre-Piece Only" if you don't need the other bits. The corners have a slight radius to make them easier to handle.
Club/Group Buy? When purchasing 3 (or more) units, the kits are just £8 each and the centres just £3 each!
Just add aerial wires plus coax (eg: RG174, RG58, Mini-8) or balanced feeder for a complete fixed/portable HF aerial solution.
If used as part of a Doublet, you will need to convert the balanced feeder to coax - best practice is to use a current balun and the shortest length of coax possible. A 1:1 Current Balun (aka: Choke) is preferred in most cases over the typically "QRP" 4:1 voltage balun found in many ATUs.
