Sloping Vee Antenna System Manual
1.3
Electrical Description
The Sloping Vee Antenna is fabricated with #14 AWG stranded copper-clad stainless
steel wire. It features a high impact resistant balun and matching network. The feedline
impedance of the antenna is 50 ohm and comes equipped with an N-type (female) coax
cable connector.
The antenna is generally mounted in an inverted vee configuration. With the centre of
the antenna rising up to 25 feet off the ground, approximately 100 linear feet of space and
a 50 foot diameter area around the mast, is all that is required for installation. With the
balun at one end of the wire, close to ground level and the terminating resistor at the
other end of the wire, close to ground, a slightly bi-directional radiation pattern results.
An alternative installation method is to mount the balun at the top of the mast with the
terminating resistor centred near the mast and close to ground level. An omni-directional
radiation pattern results from this setup.
1.4
Mechanical Description
The antenna is comprised of 112 feet of antenna wire, 112 feet of counterpoise, a high-
impact resistant balun and a rugged terminating resistor. When assembled in the
recommended fashion, the antenna has a 25 foot height and runs about 105 feet long.
The mast is guyed with 3 ropes located at two locations along the mast and spans out 25
feet from the mast to create a 50 foot installation diameter.
1.5
Scheduled Maintenance
The antenna is virtually maintenance free. Care should be taken not to bend or kink the
antenna wire or counterpoise when installing or packing antenna.
1.6
Corrective Maintenance
Generally, no corrective maintenance is possible or required. If one of the components of
the antenna are severely damaged, it must be replaced by a new component or have the
antenna replaced completely.
