Brett:
the coax with the foam dialectric was the thicker RG8U type, and the foam
dialectric was one of the reasons why I hesitated to use it for this
installation, even though it was thicker. There will be some bends we'll
have to work around, which is why I have decided to go with the Belden RG8X.
Thanks much, and 73 from Tom Behler: KB8TYJ
