Gary:
I agree about the FSL's. My flag kit can be installed in total darkness in 10-12 minutes, as Jim Renfrew witnessed a few weeks ago. There can't be much difference between that and setup of your FSL Walkers (homage to Star Wars). The deltas / loops are really not big for the cliffs. You could put 10 of Tom's deltas in Rockworks 4 if you had supports. I could make my 18x18 flag 6 times longer if desired. And my jury is still out on the active whip after listening to the recordings of weaker stations. Nick may have to be a big spender and go for the 6' or 10' element. I'd be curious about using the standard 102' cb whip which should mount onto the AMRAD unit.

Your active whip provides generally good performance in covering the entire band, and excels in quick setup and weather survivability (as we all found out on the "day of the drowned rats"). The FSL's do require manual tuning (with the related weather hassles), but they provide unexcelled low band performance, extremely quick setup and have a huge advantage in performance for the compact size (they can be set up in one square yard of flat space). Of course, all of these antennas get a DU-DXing performance boost when they are deployed at an ocean cliff site, with its solid-rock attenuation of back-side domestic signals and transoceanic signal boost. Related to this, I hope that you will post the results of your July 11th comparison of the ocean cliff propagation with that of the sea-level campsite nearby (in which the Rockwork 4 DU-DXing results kicked those of the sea-level site "off of the cliff"). 73, Gary DeBock (in Puyallup, WA, USA) _______________________________________________ IRCA mailing list [email protected] http://montreal.kotalampi.com/mailman/listinfo/irca Be sure to register now for the Joint DX Convention Kansas City, September 9 to 11.
