Wildlife Materials International, Inc.
The
MINI 2
Element
ANTENNA
with
BIG WMI or OTHER brand receivers
The MINI 2 element yagi directional Antenna is SMALL, compact and EASY to use. At half the
size of a 3-element antenna, the MINI 2 gives a good direction. The user can also REMOVE this antenna
from a receiver. If needed, the user can switch to the bigger 3-element antenna for LONGER range.
This small antenna works with all receivers. It attaches beneath WILDLIFE MATERIALS’ small,
compact TRX-3S, TRX-10S, TRX-16S, and TRX-48S Receivers, with a small padded carrying case
available for the receiver/antenna. This miniature antenna works best when mounted directly beneath a
smaller receiver. However,
the user can hold the MINI 2 in one hand while operatin
g WMI’s larger
TRX-64S and TRX-1000S Receivers as well as other brands of receivers.
When ordering, please specify whether you want to use the MINI 2 Antenna with a) a
new small
WMI
receiver, b) an
already-in-use small WMI
receiver, or c) the
larger TRX-64S, TRX-1000, TRX-2000
Receivers or other manufacturers receiver
.
In this last instance,
$5.00 extra
will be charged for the
needed connective assembly and 4 foot cable.
DESCRIPTION:
Folding elements are made of black copper-clad fiberglass. Each el
ement’s dimensions: 7.0-
inch length, .75-inch width, and 0.062-inch thickness.
A folding Velcro handle projects 3.5 inches below the antenna when opened. When
collapsed, the handle separates into two parts, which lie flat against the antenna bottom for
storage.
The antenna’s design is based on the continuous loading principle.
TECHNICAL SPECIFICATIONS:
GAIN
-- 3 dB (gives 10-15% less range than the 3 element Yagi antenna)
DIRECTIVITY
-- Front to back and front to side ratio 12 dB or better
INPUT IMPEDANCE
-- 50 ohms nominal
BAND WIDTH
-- good direction for 3 MHz, so one antenna can be used for 216-219 frequencies or 219-
222 frequencies. Standing Wave Ratio is less than 1.5 for bandwidth.
ADAPTABILITY
-- Attaches to bottom of TRX-3S, TRX-10S, TRX-16S and TRX-48S Receivers
