Multi-Element Inverted "L" Antenna using an ICE-180 Matching Transformer is an 'interesting and 'tempting' Idea. Mount the ICE-180 Matching Transformer on a Ground Rod and use Four Separate Inverted "L" Antennas with a Space Bar at the Base giving 3"~6" between the Vertical-Up-Legs of the "L"s. Beyond this Rig the Vertical-Up-Legs Tops and the Horizontal-Out-Arm Ends separately and independent from each other. Don't fall into the trap of thinking that the "separate" antennas function as separate antennas. eg: 2 dipoles running at right angles to one another (a + sign as viewd from above) and fed together does not result in a near omni antenna, but rather as a single dipole run at 45 degrees to the "+" configuration. Now, if you were to remotely switch each antenna, that would be a different story. Dale Hiya... Too bad there is no way to "remotely" switch taps on the ICE-180. You'd have to go out and physically disconnect all but one receiving wire from the unit. Then you'd have to go back out and switch 'em around when you wanted to switch. Not much fun, especially in the rain. ![]() Of course there is a way to do this. You could use relays to switch the taps. No way to remotely switch the taps without addition work and hardware that probably wouldn't be the best use of those resources. Wouldn't I be better off if I just set up additional "proven" antennas to my six position switch. I'd say there would be a better chance to benefit from completely different antennas to chose from via an antenna switch rather then setting up relays for the taps on the ICE-180 to other wires that may or may not do something good ???

Sure thing. I was just answering the assertion that there is no way to remotely switch taps. Just use the lowest impedance tap and be done with it. -- Telamon Ventura, California |
