Only a few a year!The antenna had an embarrassingly high Q, but because of its low inductance it resonated in the HF band and could only be tuned from 2500 to 4100 kHz. A more successful antenna was made from three 40-foot lengths of aluminum grounding wire. Does a random wire HF antenna (RECEIVE-ONLY!) require a counterpoise? I'm making an 84 feet (1/4 wave) random wire antenna to hang outside my house that I will be using ONLY for reviving HF transmissions on the 80, 40, 20, 17, 15, 12, and 10 meter bands, received through my Software Defined Radio.They receive quite well up through the 30 meter band, but at the higher frequencies they behave more as omnidirectional antennas. At 20 meters and above they don't hear much, but I believe that if a preamp were to be placed at the feedpoint they would probably respond well right up through the 10 meter band.Ever been in a situation where your antenna transmits well but on receive is quite noisy? Wouldn't it be nice to use a receive-only antenna with your rig eve...Dec 17, 2009 · The HFpack HF Portable Antenna Shootouts compare a variety of HF antennas for maximum gain and performance in the typical HF Portable Antenna environment, applicable to QRP and QRO power levels.

This will be a strictly receive only MW/HF antenna, so I'm just wondering about some potential arrangements. I guess this could be considered a "beverage" type antenna? I have a pretty good length of just "random wire" that's maybe around 80' long. I'm considering routing it outside, up a corner of my house behind the vinyl siding and then ...Methods of Tran smitter/Receiver Interface [Power Level Function Number] The result is a saving in land area for the DM and TM SPIRA-CONE antennas with respect to conventional antennas.

I have been experimenting with some Receive-antennas for the Low HF bands (80 and 160 meters is "low-band" to me). I discovered these popular antennas from other Hams at the Contesting Club (Potomac Valley Radio Club) I belong to.Nearly all the serious Contesters in PVRC, and all of their Superstations, have Receive-only Antenna options for the lower Bands.They receive quite well up through the 30 meter band, but at the higher frequencies they behave more as omnidirectional antennas. At 20 meters and above they don't hear much, but I believe that if a preamp were to be placed at the feedpoint they would probably respond well right up through the 10 meter band.receive antenna for weahter satellites $299.95 : free shipping 1 in stock : dclbnc : hustler dclbnc: bnc plug 40-999mhz monitor ant w/50' low loss $43.95 1 in stock : dcx : hustler dcx: discone monitor antenna 40-999mhz $30.95 out of stock : mog : hustler mog: clamp mount mobile scanner antenna w/cable $20.95 2 in stock : morb : hustler morbIs there a simple, DIY, antenna suitable for HF receive only?

Jul 06, 2015 · Airspy with Ham It Up. For HF (3 to 30 MHz), you need to use different antenna than on VHF-UHF. General rule would be that the antenna dimensions (length) should be comparable to the wavelength of the radiation. This is required for the efficient reception. The wavelength corresponding to 3-30 MHz would be 10-100 meters. Apr 09, 2016 · End fed HF wire antenna. Published on April 9, 2016. April 29, 2016 by pa1ejo. For a HF antenna you can make a half wavelength dipole, but the problem is that it is only resonant at the wavelength you design it for unless you insert some loading coils. Moreover the center feeding on a half lambda dipole is not an easy option unless you have two ...
