Active loops - another Month's use.

I have been running two crossed active loops for well over a month now as well as the e-field active that has been up for about 10 years. Living with several antennae is always interesting, the ability to instantly compare always useful. For WSPRing all have virtues, the very broad e-field is always there as a reference of known sensitivity while the directive loops are quieter on the low bands. For size, very low cost and stealth the loops are very hard to beat, they also seem to receive at least as well as a top loaded Marconi on low bands.

Recently I have been testing several alternative broadband loops against the bandpass loops, so far there is a considerable gap in performance however it is work in progress! WSPR is a very powerful aid in this work, multiple signals on most bands from many directions and at relatively low levels most of the time.
