I recently took delivery of the 6m carbon fibre mast from Sotabeams. Planning on getting together a extremely lightweight and compact kit for portable radio. Starting with a simple choke balun for QRP dipoles and verticals. Parts used in this build are:
T68-43 toroid
About 50cm of RG-174
2 x 2.5mm banana sockets
One BNC female chassis plug
Small enclosure
The RG-174 fit through the toroid 9 times which should provide adequate isolation and common mode current attenuation.
The hydration technique used was probably the most important step. 🙂
