[TowerTalk] CC XM240 above a big Tribander

[Wayne Kline]

 Interesting Mike ?
 
  I replaced  my  Hi Gain  3 element with an XM240 and it's insulated elements  gave me no top loading for my shunt feed tower ( only boom @ DC ground)
Question ..... Di the grounding have any effect  on the  antennas Band  width  or  Front to back ?
