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

Antenna 40 Meter Links →
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

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band
