I did not model this with any antenna modeling software. I did it the old fashioned way

The 3 element fan dipole works very well at covering all the bands 80-6 meters, while using a tuner on the non-resonant bands

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
