I have +20 links with jrc24extreme and duplex versions and they are awsome.
Ex.: 12km link 10dBm tx-power i get -72dBm signal.
Looks like you have a damaged pigtail or radio card or cable. To debug these links i use a groove pluged directly to the antenna.
That is why we gather in this forum! 
Wonderful idea, I’ll try it out as soon as possible.
yes there is no way to be signal like that…if you have clear LOS. So the groove is best way to test it…we use mostly jirous antennas…till now no problem(knock, knock:D)
hello to all
