A Doublet antenna is often used very effectively as a multi-band HF antenna by many amateur radio operators . It consists of a dipole like geometric structure but the wire length is not resonant on practically any of the operating bands . It requires a certain length of open-wire transmission line connected to the feed-point of the antenna .

For an average 8 foot antenna mounted on an average vehicle, and using an estimated ground losses, the efficiency ranges between .2% on 80 meters to maybe 80% on 10 meters . These figures are based on data taken from Chapter 16 of the ARRLAntenna handbook .
This is an all-band HF vertical antenna for amateur ham radio . It is the latest version and is regarded as military-grade due to its high performance capabilities . We have enlisted a few important details below: You can use it to tune all frequencies, including MURs, EmComm, NGO, government, and marine . It can cover all bands from 6 to 80 meters .
It performed well, in spite of poor efficiency, but efforts to duplicate the design for amateur operation failed . (2) Antenna Research Associates developed the loop into an excellent small communications antenna and patented it in 1967, and Technology for Communications, International (TCI) also developed a version .
The half-wave dipole is a common ham radio HF antenna . Now let's look at the classic center-fed half-wave dipole in free space . At the resonant frequency, the antenna has an impedance of 73 Ξ©, purely resistive . The SWR can be calculated by taking the ratio of the impedance to 50 ohms, giving SWR = 73/50 = 1 .5 .
The horizontal portion of this ham radio HF antenna should be at least 60% of the overall length, for best performance . Common Mode RF Chokes For TheHam Radio HF Antenna Common mode RF chokesare described in detail in another page of this site on the "classic" ham radio dipole .

The DX Flagpole Antenna is an HOA + XYL approved, No Radials, stealth HF antenna system that offers you Real DX from 160-6M including WARC bands . The DX Vertical is our non-stealth OCF HF vertical dipole antenna .Choose an antenna, an antenna bundle (antenna + atu) or create your own in your cart .

SWR or Standing Wave Ratio is a measurement of antenna efficiency . When you transmit you are sending Radio Frequency energy along your feedline (usually coax) to your antenna . The antenna then converts this RF energy into Electro-Magnetic energy which is radiated into space .
One of the best kept secrets of Amateur radio antennas are either the box, or delta loop antennas . Resonant antennas cut to the exact frequency, in the middle portion of the band, and used with a tuner of sufficient size, can tune several bands . The formula used to find a full wave loop antenna is 1005 / FMhz .
