Perfect for making inexpensive ham radio dipole or inverted Vee
antennas! Works great for Shortwave Antennas and Prepper Antennas.
Design for durability and light weight the center insulator incorporates
a SO-239 connection for your coax cable. The one piece design offers
weather tight construction and provides a drip shield to protect the
connection. A handy hanger mount is molded into the assembly. Made from
ABS Copolymer with a 20% Glass Fill. The color
and design hides well in trees and against common roof colors. Perfect
for hiding from the nosy neighbors or home owners associations.
Handles Full Legal Power
The center insulator body is approximately 3-1/2" x 1-1/4" with the
connection wires being about 6-1/2" end to end. End insulators are
approximately 2-1/32" from outside ear to ear with the diameter about
1-1/2" edge to edge. Deep ribbed construction of the end insulator
provides increased surface path to ensure reduced power leakage.
To assemble and solder the wire to the center insulator, push the wire
through the end hole and wrap wire around the connection wire. Hold
pliers close to insulator to service as a heat sink and solder outer end
of wire and connection wire together. You can make a fan dipole with
this center insulator by passing more than one wire through the hole.
Some builders will tie the wire off at the hole and then connect the
antenna wire to the connection wires with "wire nuts" which makes for a
no solder temporary antenna setup.
In the the book "Novel Antennas" published by RSGB, the Budwig HYE-QUE
center insulator is used for connecting to ladder line, it makes a great
method to connect your coax to ladder line as shown below.
Keep this dipole kit, a roll of light weight wire, and some coax cable
together and you are all set to make a handy antenna for emergency
operations, in a time of need for bugging out for your ham rig or
shortwave receiver, or as a camping antenna. Perfect for bug out bags
and shelters with the super light weight design and small size.
The formula for building dipole antennas is 468/Freq (in MHz) and then
divide by 2 to get each leg length, ie: for 40 meters it would be
something like 468/7.050 for 66.38ft/2 = 33.2 feet per leg. For a
Inverted Vee antenna deduct about 5% from each leg's length.
