Butternut HF2V 40/80 Meter Vertical
Height antenna 32 ft - 9.8 m, Impedance Nominal 50 ohms , 2 kW PEP on all bands, Bandwidth for VSWR 2:1 or Less 40m - entire band 80m - 90 kHz

MicroVert Antenna
The MicroVert antenna, designed by , DL7PE, is a short, base loaded antenna that uses the coax shield as a counterpoise
Multiband Semi-Helical Inverted L Vertical
This is my attempt to build an antenna for 80 and 40 meters that will accommodate my installation limitations
Opposite Voltages Fed Two Element Array
Both elements are voltage driven, in opposite phase ,from the feedpoint of element 1 driven there is a 1/2 wavelength cable electrical wavelength to the feedpoint of element 2 reflector
Stealth Multiband Vertical 40-80mt
The Spiderbeam pole is quite a bit more substantial than the fishing rod types that I'd used in the past, but it's still light enough to take up and down in a minute
Vertical fishingrod antenna
This vertical antenna is based on the Ground Plane theory too, with use of the base-loaded radiator

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
