What is the Best Direction to 'Point' a Sloper Antenna for DX ?
Given an area where you could locate a Sloper Antenna with a Tall Mounting Pole "Top-End-Feed-Point' and the ability to move the Bottom-Far-End around the full circle of 360 Degrees. Where would you place 'Point' the Bottom-Far-End for the best DXing ? [ N ? E ? W ? S ? ] & WHY ? Given that it is claimed that in general the Sloper produces it's best reception in the direction of the Bottom-Far-End. Coax Cable to the Feed-Point and Top-End-Feed-Point. Thinking of Rigging a Par Electronics EF-SWL Antenna as a Sloper or buying one of these Pre-Make Slopers. http://www.grove-ent.com/ANT8.html Alpha Delta DX-SWL Sloper Antenna http://www.universal-radio.com/catalog/sw_ant/0799.html Eavesdropper Sloper Antenna http://www.universal-radio.com/catalog/sw_ant/0013.html i want to know ~ RHF |

In dealing with such unstable propagation as we had in the last few years a single antenna may not be sufficient and re-orienting it may not be enough. Over here,in NYC I tried using a commercially made sloper antenna in the early 90's and didn't see it performing substantially better than a simple random length wire. That applies only to my location,that is. . . The best antenna I EVER had was a home-made T2FD. Much quieter,had some gain and it was absolutely omnidirectional as far as I know. It used a 9:1 balun transformer from Palomar (sadly they stopped making it). Reception was outstanding,considering the RFI and other man-made noise omnipresent over here. |

Several years ago I bought a used Wellbrook [UK] Universal Magnetic Balun UMB T2FD and never http://www.wellbrook.uk.com/UMBT2FD.html got around to using it. IIRC it is somewhere down in sub-basement # 3 -but- like I bought it and stuck it on a shelf and don't think that I have seen it in years. Heck I have not been down to check out sub-basement # 3 in years . . . hope that the sump pumps are still working . . . got to add that to my To-Do List on the next trip to Alameda, CA. I already have two SWL Antennas up here in Twain Harte, CA -but- neither seems bring in Europe; the Middle-East; Africa and India. |
