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
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
A simple SWR Meter is to be used at HF An SWR meter provides information about how well matched is your antenna with the transmitter and how well power is being radiated
