CHA HYBRID - MINI / MICRO
Page 17
It is predominately omnidirectional and also provides medium range sky wave propagation on frequencies above
10 MHz. An antenna tuner or coupler is required for most frequencies.
Site Selection and Preparation
1.
Select a site to deploy the CHA HYBRID - MINI /
MICRO Portable Dipole configuration. The best
location would be a clear and reasonably level
area.
2.
Clamp the Dipole Jaw Mount to the Tripod.
Refer to plates (1), (3) and (4) for the following steps.
3.
If attached, remove the Antenna Shackle (k)
from the Hybrid Base (a) by loosening the nut on
the Antenna Shackle and then unscrewing the
Antenna Shackle from the Antenna Connector
(h). Store in secure place.
Connect the Hybrid Base.
4.
Screw the Hybrid Base Counterpoise Connection
(i)
into the 3/8” antenna mount
on the Jaw
Mount until finger tight.
5.
Connect a CHA RFI CHOKE and coaxial cable or
the Integrated RF Choke end of the CHA Coaxial
Cable assembly to the UHF Socket (g) on the
Hybrid Base.
You will not be using the UHF
Socket (SO-239) on the Jaw Mount.
Raise the Antenna.
6.
Extend the CHA MIL EXT by unfolding the middle
section of the extension, fully seating it onto the
bottom section, then unfolding the top section
and fully seating onto the middle section.
7.
Connect the CHA MIL EXT to the Hybrid Base by
carefully screwing it into the Antenna
Connection until finger tight.
8.
Extend the CHA MIL WHIP by unfolding the
sections of the whip, starting with the section
above the bottom section, and ensure each
section is fully seated onto section below until
the whip is fully extended.
9.
Connect the CHA MIL WHIP to the CHA MIL EXT
by carefully screwing it into the top section until
finger tight.
Extend the Counterpoise
10.
Extend the CHA MIL EXT by unfolding the middle
section of the extension, fully seating it onto the
bottom section, then unfolding the top section
and fully seating onto the middle section.
11.
Connect the CHA MIL EXT to the Hybrid Base by
carefully screwing it into the other 3/8” antenna
mount on the Jaw Mount until finger tight.
12.
Extend the CHA MIL WHIP by unfolding the
sections of the whip, starting with the section
above the bottom section, and ensure each
section is fully seated onto section below until
the whip is fully extended.
13.
Connect the CHA MIL WHIP to the CHA MIL EXT
by carefully screwing it into the top section until
finger tight.
14.
Perform operational test.
Recovery Procedure
To recover the CHA HYBRID - MINI / MICRO, perform the following steps:
1.
Disconnect the Coaxial Cable from the radio set.
2.
Lower the antenna to the ground.
3.
Disconnect the Coaxial Cable from the Hybrid Base (a).
4.
Carefully roll (do not twist) the Coaxial Cable.
5.
Untie the Paracord from the Hybrid Base and Antenna Wire (b), as applicable and wind on line winder.
6.
Disconnect the antenna from the Hybrid Base.
7.
HYBRID MINI: Roll (do not kink) the Antenna Wire and secure with a short length of Paracord.
8.
HYBRID MICRO: Wind the Antenna Wire onto the Line Winder (e) and secure with attached shock cord.
9.
CHA MIL EXT: Starting at the bottom, pull the section apart from the section above and fold the section above
over the section below. Repeat until all sections are apart. Secure the sections together with provided sticky
strap.
