PRO-67-B V.2.S

PRO-67-B

The high performance of your Mosley PRO-67-B can only be achieved if this beam is assembled in accordance with the
instructions in this manual. Substitutions of materials or modification of design will greatly lessen it’s performance.
We recommend that you read through the assembly instructions and familiarize yourself with each step before assem-
bling your antenna.
