Musings on the miracle whip design running 5 Watts QRP


On 15 metres a distance of about 700 miles for a 439 report, I gave him 559 in exchange. We were both running 5 Watts QRP

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

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
