The NCTM-155 is a Stand with manually adjustable height. The NCTM-155 is manufactured from non-conductive material to minimise RF influence.

The NCM-155 has been produced to allow Bilogs to be mounted at 1.55m height and allow the antenna to swing into vertical polarisation without interference from tripod legs. It consists of a 91cm square base of nylon to which the main sections of the TRX-36 are attached with an extender unit to reach the 1.55m without adjustment to the limit.
