40 meter linear loading rotable
The linear loading assembly functions also as a supporting guy to prevent element sagging. I think the M-Squared folks were very creative in this
40m center loaded vertical antenna 5 metres long
Vertical of 5 meters with central traps for 40m
A Limited space HF antenna review
A 40 meter half wave dipole antenna compressed into such a small size
A Linear Loaded Vertical antenna for 40mt and 80mt
The vertical antenna looks to be the perfect low angle radiator, except for one thing the height of a 1/4 l at 80 metres is 20 metres, or 66 feet, which is not practical to construct
