An instruction sheet is not provided with the 86LM coaxial antenna extension kit. This kit is designed for use with the 312HM, 412HM, 423-315LM(323LM), 412HM, 422LM and 850LM.
There are two models available, 86LM or 86LMT. The kit includes only the L-shaped bracket with the coaxial connection and a length of coaxial cable. 86LM has 15', 86LMT has 25'. It does not include the brass antenna.
You should use the existing antenna from the receiver. If the antenna is needed, you must order part number 041C3196 separately. For the 850LM, the special bent antenna, K77-36541, must be used. Because this antenna is specially tuned for the receiver, do not use the brass antenna or allow the antenna to be bent from its original shape.
