2 element cubical quad for static mobile


Posted elsewhere, but thought I would share here as well.
Made this for static mobile use, as I have had to take my sgm down at home due to council complaints. It all comes to bits and can be carried in the car with rear seat folded down, takes me 10 mins to assemble and get on air.
So far working very well, can usually get back to everything I can hear, even though I only use radio power (dx5000 V5).
