Linear loaded dipole for 7 mhz
7 MHz a standard horizontal dipole requires approximately 66 feet of wire,and with center and end insulators, ap-proaches 68 feet between rope supports
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
