Antenna offset corta di
Ho implementato due versioni quella fino a 80m e quella fino a 160m.I calcoli sono stati eseguiti su carico di alimentazione di 300ohm per cui e' necessario adattare l'impedenza con un balun 6:1 per utilizzare la discesa coassiale a 50 ohm

Double-L Antenna For 80/160
The antenna is a center-fed half-wave vertical with about 70 feet of vertical length with the remainder of the top and bottom of the antenna bent horizontal and parallel to each other. The antenna looks like a squared-off letter C fed in the middle of the vertical part

Dual band 80/160 Antenna Commutabile
L'idea per accedere a questa interessante porzione di spettro e' stata quella di sfruttare un braccio del dipolo e il tratto verticale della discesa che formano una antenna a L. Per funzionare una antenna a L necessita di un riferimento di terra il migliore possibile

Base Loaded 160M Half-Sloper Antenna
Construction is pretty straight forward, drill end caps for 3/8-24 hardware ring connector on end of wire that was fed through PVC tube for cap.wrap wire around coil form

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
