The SINGARS uses Hardware Encryption, in addition to frequency hopping mode to ensure that all traffic remains secure.
With the an omni antenna and a spectrum analyzer you can spot and triangulate frequency hopping transmissions, but you aren't going to be listening in without obtaining all the crypto keys.
The fact that they claim they were able to crack it is only possible if they obtained a fully operational radio with loaded fill device with that time periods keys. Then they would have to know what key goes where to ensure that they're sync with the rest of the net.
The only other way would be if the Israeli's were just hanging out in plaintext and single channel mode.
