20 METER BAND
DIPOLE/INVERTED V WIRE ANTENNA
WITH MFJ-918 BALUN AND
100 FEET OF SUPPORT ROPE
|
-
This antenna will provide
reliable communications in a permanent or portable
installation.
-
Completely portable. Will
easily fit in a 'bug-out bag'.
-
Can be installed or taken
down in minutes.
-
Antenna wire is 14 gage,
insulated, stranded, copper wire. Regardless of what you
may hear, insulated wire has little or no effect on the
received or transmitted signals when used at HF (high
frequency).
-
Solid, copper coated
steel wire is very difficult to work with and will
kink and break at the kinks. Stranded copper wire is
very easy to work with and has no 'reel memory'.
-
Copper coated steel wire
will fail when the copper coating is damaged and the
steel is exposed to the elements.
-
Bare copper or steel
wire cannot be used when ran through trees or other
foliage. This will detune the antenna and
cause high SWR when transmitting and a loss of
signal when receiving..
-
This antenna will be shipped, completely
assembled with dipole
dimensions. The antenna is tuned for the low end of the
band (longest wire section). If installed as an inverted V, It may need to be
shortened by about 5%. The exact length will depend on the desired
resonant frequency, height above ground, and proximity to other
objects such as trees, buildings, etc. A table will be included that
shows recommended lengths for resonant frequencies.
The ends of the antenna (attached to the
MFJ-918 balun) are soldered and weather proofed with heat shrink
tubing. The ends
(attached to the
insulators) are just twisted together (Not soldered) allowing for
easy adjustment.
If you adjust the length, just untwist
and pull more wire through the insulator and wrap it back on itself.
There is no need to cut the wire. Be sure to adjust both sides
equally. A table will be included with recommended lengths for
inverted V and dipole configurations.
-
100 feet of 100% polyester rope support rope
(DacRope) is
included and features excellent UV and abrasion
resistance and low stretch. It's also strong with a 380
lb. break strength.
Comes fully assembled. Installation instructions included.

MFJ-918 Balun
|
|
The 1:1 Current Balun was designed to
replace the center insulator of a dipole antenna. It is made up of 50
Ferrite Core Beads placed onto a 13-inch piece of RG-303 Coax. Operates 1.8
to 30 MHz.
The coax and SO-239 connectors have
Teflon for maximum insulation and extended life of the product.
The MFJ 1:1 Current Balun is enclosed in
schedule 40 PVC pipe for maximum strength and protection.
Unlike other baluns, the MFJ-918 makes a
direct electrical connection to the antenna with #14 copper wire.
The MFJ Current Balun will reduce or eliminate stray RF often found on coax.
This stray RF can cause burns and other problems with electronic equipment
in ham-shacks and vehicles. Stray RF also results in a loss of radiated
power from the antenna, which will lead to a great reduction in signal
strength.
