You could be electrocuted if the antenna gets near or contacts overhead power lines.
MINI and MICRO bases are for stationary use only. You can even combine a CHA HYBRID - MINI / MICRO base with two CHA MIL whips, two CHA MIL EXT whip extensions, and a Chameleon Antenna Jaw Mount and Tripod to create a 34’6”...

Hybrid Base, Mini (left) and Micro (right). Isolation loop An Isolation loop is permanently attached to the Wire Connector (f) end the CHA HYBRID MINI Antenna Wire (b) and both ends of the CHA HYBRID MICRO Antenna Wire. d. Carabiner The Carabiner is a removable pear-shaped stainless steel hooks with a spring-loaded gate.
The Insulator is permanently attached to one end of the CHA HYBRID MICRO Antenna Wire (b). Wire Connector The Wire Connectors are located at one end of the Antenna Wires (b). UHF Socket The UHF Socket, SO-239, is located on the side of the Hybrid Base (a). h.
table, decide which distance column (Ground = 0 to 90 miles, Short = 0 - 300 miles, Medium = 300 – 1500 miles, Long > 1500 miles) best matches the distance to the station with whom you need to communicate. Then, determine if the OWF is in the lower (↓...
8. Using a Bowline or similar knot, tie the end of a long length (25 feet or more) of Paracord to the Carabiner from step (5). 9. Using a throw weight or other method, loop the Paracord over the support that is closest to where the radio set will be located.
unidirectional towards the end of the antenna wire as the frequency increases. The Sloping Wire requires one support and should be mounted at a height of 25 to 40 feet for best performance. A counterpoise wire, with a length of 20 to 40 feet, is recommended. If a counterpoise is not used, the coaxial cable must be 25 to 100 feet in length, as the shield of the coaxial cable provides the counterpoise.

Extend the Counterpoise. 17. Perform operational test. 16. If using a counterpoise wire, extend it along the ground under the antenna. Manpack Vertical The CHA HYBRID - MINI / MICRO and CHA MIL WHIP Manpack Vertical configuration, see figure (4), is a broadband short range HF/VHF-LO antenna.
It also provides sky wave propagation, especially above 12 MHz. Using the optional CHA JAW MOUNT, the Portable Vertical can be mounted on almost any support, such as a camouflage netting support pole, fence post, picnic table, or the optional Chameleon Antenna Tripod. The antenna works better when mounted above the ground, but will provide satisfactory performance if ground mounted.

Using the optional Jaw Mount, the Tilted NVIS antenna can be mounted on almost anything, such as a camouflage netting support poles, fence post, tree limb, or the optional Chameleon Antenna Tripod. The Antenna Wire (b) or a stationary vehicle are used as the counterpoise in this configuration.
The CHA HYBRID - MINI / MICRO base with two CHA MIL WHIPs and two CHA MIL EXTs Portable Dipole configuration, see figure (8), is a broadband short to medium range HF/VHF-LO antenna. When used with the optional Chameleon Antenna Dipole Jaw Mount and Tripod, this configuration provides the ultimate in versatility and portability.
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 7. Connect the CHA MIL EXT to the Hybrid Base by 1.

RF Choke Assembly. The CHA RFI CHOKE will prevent, greatly reduces or totally eliminates the RFI carried by the coax cable. It can be installed either at the antenna feed point or right behind the antenna tuner. This accessory is highly recommended if you are not using the Chameleon Antenna Coaxial Cable Assembly.
