I've used these fibre glass telescopic poles before but I have the "SpiderBeam" variant which is more or less identical I guess, however I never thought to use it in the way this guy has; I've only ever used them for EFW on MW and HF, typically with a air wound loading coil at the base on a PVC waste pipe. I did share this on the RN forum some time ago. I later used a toroidal FT 250-2 core with much success and made a simpler and easer installation.

I guess this would be ideal for a pop-up weekend station transmitting from a high wooded area.
