Putting up an Alpha Delta DX-SWL Sloper antenna, can the high end be mounted to a metal tower, or do it need to be insulated from the tower. Since it comes with it's own .Arrange the sloper antenna so it will not be in close proximity to any guy wires, metal gutters, roof tops, other wire antennas or aluminum house fascia. A separation of at least 10 feet is preferred.
All hardware used is of 18-8 Stainless Steel, and requires no further protection. This completes the installation of your ALPHA DELTA MULTI-BAND SLOPER ANTENNA. Please review the .Turn on your shortwave radio (mine is a Sony ICF-SW 7600G). Extend its telescopic antenna and place it near and parallel to one side of your homemade tuned loop shortwave antenna. tune . This is for the person who opens up the box and wonders about the best way to hang the included long-wire auxiliary antenna. Equipment: Tecsun PL-660 SW/AM/FM/Air .I’ll show you how to put up simple, effective shortwave antennas that are almost invisible. If your local communists can’t see it, they can’t object to it, since the rationale for their anti-antenna .
A basic formula for a dipole antenna (not an L antenna) would be to divide your operating frequency in MHz (e.g. 15 Mhz) into 468. That will give you the length of your .
DX-SWL - SWL Broadcast Sloper - Covers the 13, 16, 19, 21, 25, 31, 41, 49, 60, 90, and 120M short-wave bands plus the AM broadcast band. Sloper design provides outstanding reception ."The Search For The Perfect Shortwave Antenna" by N4UJW master Hamuniverse.com. Follow these simple plans to build a multiband shortwave antenna and be on your way to .
Arrange the sloper antenna so it will not be in close proximity to any guy wires, metal gutters, roof tops, other wire antennas or aluminum house fascia. A separation of at least 10 feet is preferred.
I had a couple of slinky antenna for years. They worked great! One was two slinkies soldered end to end, and stretched out on a rope. It was 3 originally, but I had a nearby AMBC station that was strong enough that it caused problems on all my receivers, either adding a level of hash on lower freqs, or in the worst ones, causing audio to be heard in the background .
The whole grounding issue is why I have not, to date, put up an external antenna. I make due with an attic mounted antenna. My basic understanding is that the metal mast should be grounded to earth. . in the last forty years and have erected antennas for all sorts of SWL, scanning and ham use, I have buried a ground stake outside the room or .Ordinarily, if you don't have a sizable garden space or you live in a flat without one at all and cannot run a long wire, an HF shortwave antenna might feel off-limits. That's where the X1-HF Antenna comes in, designed specifically for use .
shortwave spectrum. The slope angle should be from about 45 to 60 degrees for best performance. 4. Arrange the sloper antenna so it will not be in close proximity to any guy wires, metal gutters, roof tops, other wire antennas or aluminum house fascia. A separation of at least 10 feet is preferred. The"All antennas work." The question is to what extent. Your design will work, but you'll need to set your expectations appropriately. The proximity to your home, the home wiring, the devices inside your home will allow this antenna to couple with things you don't want it to couple with -- and as a result it will pick up a great deal of local noise, possibly rendering your receiver nearly unusable.
Depending on the bracket material you choose, an antenna may perform differently than you expect. The same is true of the mounting surface. For example, metal reflects radio frequency (RF) waves. If you use a metal . I would consider a VHF/UHF antenna over a huge metal roof ground plane similar to an HF antenna over earth ground. When its lower than a few wavelengths and at multiples of 1/4 wavelength like 1/4, 3/4, etc, the .
BOW OUT FROM BRACKET VERTICAL ELEMENT Eavesdropper SWL "Sloper" Antenna Pre -assembled "sloper" antennas are a relatively new phenomenon on the shortwave listening scene. First on the scene was a model by Alpha Delta. It was their first short- wave listening antenna and it functioned well enough. Fortunately, however, like all inno-A bumper mounted 102 whip will greatly outperform that roof mounted 19" helical in every way, for example. Bumper mounted 4ft firestik probably equals the 19in on the roof, or nearly so. A 19in antenna will perform like crap compared to almost anything longer, . Note--Adjust the orientation of the antenna mounted on this pole until you get the correct angle to receive a clear image from the antenna.
