The J-Pole or Half-Wave Zepp Antenna
The Half-Wave Zepp is an end-fed half-wave antenna. That is, it is a piece of wire one-half wavelength long with the feedline connected at one end
The versatile end-fed wire
A length of one quarter wavelength ie 20 metres on the 80 metre band is commonly suggested. Though such antennas do work, an extensive ground system or counterpoise is required for best performance
End fed portable
Questa è un'antenna filare End Fed lunga 16,2 metri e alimentata tramite un trasformatore a toroide UNUN con rapporto 9:1
Delta Loop vs End Fed Half Wave on 20m
Intrigued by a German OM positive experience with a 20m delta loop
Multi-Band End-Fed Antenna Limited Space
Using for multiband end-fed is a 1:49 to 1:60 impedance transformer that feeds half a wave of wire fed at the end
End fed 6 - 40 Meter Multiband HF Antenna
End fed HF antenna The end fed feature adds portable convenience, but does present another issue.The problem with an end fed half wave antenna is that the antenna presents high impedance
