Gary, K9AY, has made life simpler for us. I sprung for the model AYL-4. This
includes a 4-direction loop system. The switch box contains an 8 position
switch to remotely change the value of the termination resistor out at the
antenna to optimize the F/B for each band of interest. When the preamp
switch is moved to "on," you get a high-quality 15 db preamp, a filter with
a passband from 1.75 to 4.5 mhz +/-2db, and stopband filters at -55 db @ 7
mhz, and -50 db below 1450 khz. If you want to listen below 160m or above 5
mhz, you just leave the filter/preamp switch off. This antenna is a joy to
install, (requires one old man, and some planning) and meets the advertized
specs.
I am very pleased with the high-quality of the materials and workmanship in
all of Gary's products that I own. The AYL-4 will beat a 600' Beverage on
rare occasions (like last Friday night) and is a great addition to my RX
arsenal.
