[TowerTalk] Paint Fiberglass antennas?

[Grant Saviers]

The SteppIR poles are coated, and there is no recommendation for 
additional painting, but some folks do that.

I was a bit concerned about the UV longevity of the heat shrink that 
goes over the tapered sections joints and placed a layer of 3M silicone 
self fusing tape over them on my 4L.  That is in great shape after 8 
years, as is the FG coating.

The trombone elements IMO are effectively linear loading when the tape 
extends back towards the EHU on the 30 & 40m capable antennas.  From 
experience with my newer DB36 on 30 & 40, it is  sensitive to nearby 
loading effects, so there might be some retuning needed from a paint job.
