|Subject:||[TowerTalk] Strengthening Insulated Push-up Pole Base|
|Date:||Fri, 02 Jan 2004 16:52:23 -0500|
I am thinking of putting up one or two 60' push-up poles isolated|
from ground as part of an experimental 40/60/80/160M antenna system. The bottom section of the push-up pole is 3".
If I set a 3" ID section of thick-wall PVC inside an 8" section and set them in concrete would y'all recommend concrete, sand, or ??? in between the sections of PVC?
I am wondering how the PVC may react to different substances, what would provide the best strength, if I want flexiblity between the sections, and what might enhance the insulation value of the PVC.
Thanks! & 73, doc kd4e
