Antenna Transmatch tuner Links →
Accordatore da 10mt a 160mt
Da 10 a 160 m.,C1 - C2 = 700 pf,L1 = 40 spire di filo di diametro 2 mm su supporto di circa 5 cm.,S1 = Commutatore multiplo 1 via 12 posizioni
Accordatore CTE da 27 - 430 Mhz a 14 - 30 Mhz
Con poco lavoro puo' essere facilmente adattato a lavorare sulla parte alta delle Onde Corte
Accordatore per RTX QRP
Semplice accordatore d'antenna concepito per l'uso portatile
Antenna Transmatch Tips
The SWR protection circuits in modern transceivers require an SWR of 2: 1 or less if they are to deliver the full rated power of the transmitter section

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
30 Volt Computer Power Supply Stack A bonus was that i discovered that these did not need a standby load connected to the supply to keep them running just apply mains power and close the Start lead to ground
