Adding 30 and 40 meters to the 4 Element SteppIR


Without a doubt - innovation! This antenna, despite the problems I've faced, is undoubtedly the last one I'll buy

Adding 30 and 40 meters to the 4 Element SteppIR

Antenna 40 Meter Links

40 meter shortened dipole project
I used MMANA to design this antenna the dimensions of each of the legs each side are, 40m: 7.5m and a slope of 2.5m, 30m: 7.47m, 20m: 5.69m

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
