Section 4.1: Assemble CPVC liner sections
PREPARE THE CPVC LINER
• The CPVC liner can either be bonded using heat shrink (this method is removable if you ever need to dis-
assemble the antenna) or with CPVC glue (this is permanent and the cpvc will need to be cut if you ever
need to remove it). If you prefer to use the CPVC glue (permanent) then apply the glue to the outer di-
ameter (OD) ONLY so that glue does not spread into the inner diameter (ID) before inserting into the
coupler and twisting. Work quickly as the glue will dry quickly and become less effective. There is no need
for the heat shrink if you use the CPVC glue.
• Be sure to save some glue for later, as this will be used to install the CPVC liner onto the BigIR EHU dur-
ing final assembly.
