Who else uses the KU4AB VHF / UHF loops? SQ-50 6m square loop. SQ-144 2m square loop. SQ-432 432 mHz square loop.
In 2010 I bought the KU4AB SQ-50 single loop, SQ-144 stacked loops and SQ-432 stacked loops that I used for VHF / UHF rover operations. I liked how each of the loops worked well that in early 2011 I bought a second set of the KU4AB SQ-50 single loop, SQ-144 stacked loops and SQ-432 stacked loops for VHF / UHF operations at the home QTH. The rover loops are mounted to a 10’ section of 1.25” OD 16 gauge galvanized TV antenna mast. The QTH loops are mounted so that the SQ-50 single loop is up at 35’, the SQ-144 stacked top loop is at 34’ and the SQ-432 stacked top loop is at 33’. It’s been several years since I‘v operated as a rover, so I’m thinking later this fall when this Houston heat and humidity comes back down to reality, of taking the SQ-50 single rover loop and stacking it with the SQ-50 single QTH loop. Since the SQ-50 6m loops when stacking them require a spacing of 12’, I’m going to add another 10’ section of 1.25” OD 16 gauge galvanized TV antenna mast so that the top SQ-50 loop along with the rest of the loops will be 10’ higher which will put the bottom SQ-50 stacked loop up at 32’ high and well above the peak of the roof. This should make for a nice noticeable difference with receive signals and for sure give a nice boost to my 100w signal on 6m sideband. Not to mention a bit of all around improvement with the SQ-144 stack and SQ-432 stack loops with the addition of an extra 10’ gain in height.
