160m 80m_broadband_antenna


Impedance is much lower than 200 ohms. One way to cause the 160 and 80 meter impedances to be about the same is to form the antenna into a right angle as shown below. The 4:1 balun feedpoint is 35 feet from the end

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
