Introduction; Product Overview - Alpha Antenna Alpha Loop Sr User Manual

Introduction

Thank you for purchasing the Alpha Loop Sr Antenna. We hope that you will enjoy using this
product, as we continue to receive written testimonials from Amateur Radio Operators (Hams)
who are surprised by the antenna's ability to make many long distance contacts, using low
power.
The Alpha Loop is a magnetic loop antenna that is easy to tune, has acceptable bandwidths, and
offers coverage for 40, 30, 20, 17, 15, 12, & 10 meter bands. The antenna is only 34 inches in
diameter and has a built in tuner at the base of the antenna. This antenna is so efficient that it
can be used indoors, from a porch or balcony with only a 2-3db reduction in performance.

Product Overview

The Alpha Loop Sr Antenna is designed to operate on the 10, 12, 15, 17, 20, 30, and 40 Meter
amateur radio bands. It will accept up to 30 Watts (PEP) of transmitter power on SSB. Using
the antenna's Micro-Tuner, your radio's transmission line SWR can be continuously tuned to a
match of less than 1.5:1 on any frequency from the 10 Meter through the 40 Meter band.
When manufacturing this antenna, we use only brass bolts and nuts at the connection points
that feed the antenna, as well as silver plated shield and gold plated pin connectors at the feed
point of the antenna. We then place the Alpha Match inside a High Voltage UL-Rated housing.
We put safety first and insert a nylon shaft between the knob on the front of the Alpha Match
and the 6:1 reduction drive that connects to the Variable Air Capacitor, which is designed to
keep RF burns from occurring. This design also helps to minimize your body's capacitive
interference when tuning the Alpha Loop Sr.
