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

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
A simple SWR Meter is to be used at HF An SWR meter provides information about how well matched is your antenna with the transmitter and how well power is being radiated
