Pacific Antenna 15 Watt Dummy Load Kit

Introduction

Our 10 Watt Dummy Load kit is a compact design using all through hole parts

A great first time kit to learn or improve soldering skills.  

Can be assembled with common soldering tools and techniques

Provides direct RF as well as DC voltages representing the Peak and RMS values.

Accurately measures RF Power from less than 100mW to 15 Watts with just a digital Multimeter 

Usable from DC to 60MHz

Includes all the components and circuit board.
  

Inspection and Inventory

First, check the kit to be sure all parts are included. Should anything be missing, please contact us for a 
replacement.
