Nice test it’s interesting to see the distinct differences between antennas.
ОтветитьAre the days of you doing videos with Tom Stiles over? I really miss the two of you interacting on videos.
ОтветитьTry to raise the bottom wire of your delta loop up to 1.5m or 2m(6.5 foot), I think it could help to improve the performance of your delta loop.
ОтветитьDelta will always have lower noise floor, and weaker " s " reading but signal to noise ratio makes it all up. At the house I use my 160 full wave on 80 and 160, and use the 80 thru 10 end wave for all the lower stuff. I would assume you would have better results if you could get the delta in a non compromise set up. I have found over the years because something is supposed to be better doesn't always make it so.
ОтветитьInteresting results. Thanks KJ6DQ
ОтветитьGreat test, many thanks! Robert K5TPC
ОтветитьI tried only type 1 WSPR messages, but there is a type 2 which enables compound callsigns so you can add a suffix to distinguish the antennas.
ОтветитьGreat job testing the antennas. It was cool to see the differences.
ОтветитьWonderfully done!!
I would be interested in the configuration in which the triangle peak is at the center and top of the pole. With a 30 foot pole - the two inward sloping sides would be 42' long - and the bottom horizontal section would be 59 feet long. In that configuration - the feed-point is located 1/4 wave down one of the sloping sides from the top - or 9 feet up from the bottom. The loop is vertically polarized in that configuration - and from what I understand - it is similar to a dipole - but with a about 2 DB gain over the dipole. The advantage of this antenna is broad-side vertical radiation - which provides directivity - and without the need for radials. It promises to be a good DX antenna
Totally agree with your conclusions Rob. My experiences are pretty much the same. It all depends on your circumstances. Hard to beat a loop for S/N . But the EF much more practical for POTA. Thanks for all your efforts and for sharing your results. 73
ОтветитьDelta loop has better receive ability because low noise,, And for transmit you can conclude yourself after watching this video
