[TowerTalk] XM240 Mast Clamp

[Wayne Kline]

I also Like Tyler      Opted to use the Hy-Gain/Telex  Cast mast clamps on the XM240.  This is a know issue with the original 402CD and the XM240.  Mater of fact I  use a Pair of them So I can rotate the antenna and have access for element maintenance  If need be .    YMMV      73's Wayne W3EA
