[TowerTalk] Tin roof blues (score: 1): Author: W8JI@contesting.com (Tom Rauch); Date: Tue, 12 Jun 2001 06:59:51 -0400; Hi Barry, What that might show is the radials and roof are almost perfectly coupled. If they were isolated, if there was a voltage difference, current would definitely flow. When there is no current; /archives//html/Towertalk/2001-06/msg00249.html (8,500 bytes)

[TowerTalk] Tin roof blues (score: 1): Author: k2av@contesting.com (Guy Olinger, K2AV); Date: Tue, 12 Jun 2001 10:43:59 -0400; To the original poster, one of the ground-independent multiband verticals like the R8, etc, would be quite good above a tin roof. The difficulties with ground for a vertical are 1) insufficient radia; /archives//html/Towertalk/2001-06/msg00254.html (11,731 bytes)

I have no cure other than bonding the panels together, had work and sometimes impossible. On; /archives//html/Towertalk/2001-06/msg00255.html (12,797 bytes)
5. [TowerTalk] Tin roof blues (score: 1): Author: k2av@contesting.com (Guy Olinger, K2AV); Date: Tue, 12 Jun 2001 11:31:10 -0400; RF current causing TVI in tin roofs is particularly possible when the roof is used AS the current sink or is tightly coupled with high current radials immediately above it. The amount of current/volt; /archives//html/Towertalk/2001-06/msg00258.html (14,768 bytes)

I did have an isolating balun at the feed point, made the assuption that no current =no coupling, but as you point out no current could mean perfect coupling. FWIW the higher band mono; /archives//html/Towertalk/2001-06/msg00265.html (9,425 bytes)
