For example, I put the capacitor into an empty film box. May be at antenna tuning you need change the length (in + or - ) of the L2. Counterpoises are laid on the ground. Overall weight of the antenna with its

 

mast (was used a telescopic plastic fishing rod) is a little more the 1000 gram (2.2 pound).
