SINGLE-WIRE SPIRAL ANTENNA - Nippon Antena Kabushiki Kaisha

Abstract of EP0825674 Taking the spiral circumference, C, of a single wire spiral antenna as 2.3 lambda ( lambda being the wavelength at the operating frequency), for example, the beam radiated from an axis Z perpendicular to the antenna surface is tilted.

Random wire antenna - Wikipedia A random wire antenna is a radio antenna consisting of a long wire suspended above the ground, whose length does not bear a relation to the wavelength of the radio waves used, but is typically chosen more for convenience.

Re: Single wire antenna

VK6YSF long wire antenna article - VK6YSF - Home Page The feed impedance of the end fed long wire antenna is perhaps the main consideration particularly as in this case the antenna is to be a multi-band antenna, being a useful radiator on all amateur radio bands from 80m through to 6m. If the antenna were to be a single band antenna with the wire cut to a ¼ wave length at the desire frequency this would produce a feed impedance somewhere between.

The Best Random Wire Antenna Lengths - Hamuniverse Hopefully these random wire length calculations will help us all make this 'easy' antenna work better! (Also note that here may be instances where the suggested lengths may not work exactly due to the many variables in the surroundings of the antenna, wire length variances, your tuner, it's height above ground, it's construction, etc.

My Favorite 40m DX Antenna - Ham Radio Site - [HOME] For disassembly, disconnect one side from the insulator and then roll the antenna as a single wire. Each time I changed my QTH, I had to re-adjust the length of the jumper. I just let the jumper wire hang down.

Single wire Cobwebb antenna • Last summer I built myself a Cobwebb antenna and was fairly pleased with the results. I did think it was a bit heavy and was looking to repeat the build with some lighter weight wire until I came across this article from a well-known antenna buff, G3TXQ.
