Antenna terminal to Hi-Z

Amp

Hi-Z AL Series Base Insulator Field Upgrade - pg 3/3

Holding clamp. Clamp so that the lower

Vertical end is exposed to connect Hi-Z Amp, no more.

Located so that the top of the coupler

Extends about 1.25" above the angle mount

Upper clamp, clamped at

Top of the Angle aluminum

mount

Lower Clamp, clamped in the

Middle of the PVC coupler

The standard insulator while being satisfactory

has a higher Pf value than desired. The new insulator

on average lowers the capacitance by ~55-60pf.

This will allow the Hi-Z Amp to produce from 2-3db

higher gain and therefore increasing system performance.

As well as increasing the physical spacing of the element

from the base mount.
