Transducer cables

[87Stratos]

Can you shorten a transducer cable without disrupting the signal? Mine must be 20ft long and I only need 5ft. Right now I have all extra cable coiled up, but its alot of cable to have lying on the deck.

Re: Transducer cables

Yes, Stratos, it can be done. It may require a new connector, depending on the type.<br /><br />If you have not been trained in the installation of coaxial cable connectors take it to someone who has. <br /><br />Red sky at night. . .<br />JB

Re: Transducer cables

Check with the manufacturer. Some don't want you to cut them because the resistance from the cabling is figured in with the transducer for performance. I have a scanning Interphase unit on my boat (admittedly higher tech) but they warn not to cut the cable due to likely reduced performance.

I have two fish finders. the one I want to shorten is for an "Eagle".

Hi 87<br /><br />Alaskaskiff is right. The resonance of the circuit is changed with cable length. A good tech can probably tune the finder to compensate, but is it worth all the effort and expence?

Re: Transducer cables

Yea, ditto to Schematic. And, as I have found out the hard way, when you shorten a cable like that, you later end up needing it long again, because you want to move your fishfinder, you go to sell it to someone else, and so on.<br /><br />Also, when you store the cord, do not wind the cable into coils. "Zig-zag" it in approx. 1 foot lengths each way, and put a wire tie in the middle of the bundle to hold it together. Then you can fasten it under your dash, etc. to store the extra cable.<br /><br />Sometimes when you coil the cable, it also affects the impedance of the cable (it makes it act like a transformer, electrically speaking).

Re: Transducer cables

i found out the hard way also better to coil it up and zip tie it outta the way for now
