The Gamma match is the most used matching device used for yagi beams. figures are never all high at one point. A well designed yagi has for that reson an impedance around 20..25 ohms. A Gamma-match can match impedance below 50 ohms right up to that 50 ohms wich your tranceiver wants to see.

The frequency band 5351,5-5366,5 kHz is also as*igned to am*teur radio service with secondary service status. Am*teur radio stations  using the frequency band 5351,5- 5366,5 kHz  should not exceed the maximum equivalent isotropic radiated power of 15 W  (WRC-15) “La banda di frequenze 5351,5-5366,5 kHz è anche attribuita al servizio di radioamatore con statuto di servizio secondario. Le stazioni del servizio di radioamatore che utilizzano la banda di frequenze 5351,5- 5366,5 kHz non devono superare la mas*ima potenza isotropa equivalente irradiata di 15 W (e.i.r.p.) (WRC-15).” The PNRF has been published on the attachment no. 49 of the “Gazzetta Ufficiale” on 19th October 2018, no. 244, and due to the This 2m yagi uses design data from DK72B’s excellent yagi website. The element to boom mounting used here may be of use to some as it A windom antenna for 10 to 80 meters band – a design by PU1LHP Let me first say I make no claims of originality for this item. It is intended as a simple, inexpensive solution for the newcomer to experiment across the 40m band (7.0–7.2MHz) when only restricted space is available. “A picture speaks a thousand words” so by With the rally season upon us, it is an ideal time to pick up those bits and pieces with which to experiment. The antenna described here consists of a 50R coax fed, inductor loaded 5.44m vertical section mounted on a 1m alloy tu*e driven into the ground and requires no radials although this may well depend on the local soil structure. The vertical itself is a salvaged unit (probably ex. CB) consisting of 4 telescoping aluminium sections with an extended length of 5.44m and
