trapper i'm replaceing everything but my lcg 2000 antenna, for some reason it keeps loseing the sattilite signal and wont lock on full time. lowrance told me this is what i needed to do so i ordered that cable + the tee connector, and i think there is another shorter cable. i'm hopeing i dont have to use all componants and am going to send back to lowrance unneeded cables and hope that that cable (n2kext-25bl)is one that i dont need. if i dont use it your welcome to it for price + shipping. the problem is they have sent me this cable but they haven't sent the other tee conector and the short cable yet , i got the n2kext-25bl yesterday and still waiting on the rest of the order. i'm going to work from the tee out to the power and the antenna and see what happens hopeing i dont need this n2kext-25bl.ckeck back and let me know what you think , and as soon as i get the remaining parts it wont take long and i'll know whats going on. have you checked with lowrance?there must be a shortage or something as it has been 3 weeks since i ordered these parts. also that cable alone is $60.94 counting shipping.
