A QRP DX antenna amateur radio construction projects. __ Designed by Peter Parker. Active 3 30 MHz Hula Loop Antenna for Shortwave If you have a shortwave or high frequency receiver or scanner that is struggling to capture signals with a short, whip antenna, and you'd like the kind of performance that a 60 foot 'longwire' antenna can provide but lack the space to put one up, consider ...Indoor HF Active Loop Antenna Cross Country Wireless
Indoor HF Active Loop Antenna. Cross Country Wireless manufacture an Indoor HF Active Loop Antenna with a frequency range of 20 kHz to 70 MHz with extended coverage up to 148 MHz.Medium Wave Circle Antenna advice
Antenna advice. by Graham Maynard.. Radio waves radiate from an electrically excited transmitting mast, and ripple outwards at almost the speed of light. It is displacement of the dual electrical magnetic equilibrium that transfers energy, not a tangible flow, and this is why radio signals are almost all pervasive.Antenna (radio)
In radio engineering, an antenna is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver. In transmission, a radio transmitter supplies an electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves).Wideband Active Small Magnetic Loop Antenna Signa Cor

A log periodic antenna (LP), also known as a log periodic array or log periodic aerial, is [dubious – discuss] a multi element, directional antenna designed to operate over a wide band of frequencies.It was invented by Dwight Isbell and Raymond DuHamel at the University of Illinois in 1958.. The most common form of log periodic antenna is the log periodic dipole array or LPDA, The LPDA ...HF END FEDZ | PAR Electronics | Filters for the commercial ...
The Par End Fedz are a full length half wave dipoles, but with an important difference. The coax connector is at one end of the dipole, where it is most needed.
