[TowerTalk] MA-550 Telescoping Tower Grounding and Rotator Cage

[Steve, W3AHL]

Several reference on lightning control recommend using some type of flexible grounding contacts to ensure continuity between the telescoping sections of a tubular tower.  I'm considering using stainless steel fingerstock, but would appreciate hearing of other's solutions.  

Also looking for any lessons learned on building a rotator cage (not using the MARB base).  I've seen several examples on web sites, but suspect they weren't "engineered" solutions.
