80/75 meter cage dipole

Each cage dipole is hand made with quality and care, using materials that will take the abuse of even the most harsh enviroment.

The wire used is #14 AWG Flex-Weave. Polyethylene black jacketed FLEX-WEAVETM, 168 copper strands for high abrasion/rodent resistance light weight making this a excellent choice for the 125' length.

The center connector used is the W2DU ANsulatorW2DU End-sulators

All connections are swagged and soldered, adhesive lined 3:1 heat shrink is used on all connections. 

 

The balun used is the Choke-Kit

Specifications subject to change without notice

 

24 microhenries provides an inductive impedance of 270 ohms at a frequency of 1.8 MHz.

 

(multiply Inductance in microhenries by Frequency in megahertz by 6.28 to get Inductive Impedance in ohms)

The cage material is 7" round X 1/4" thick white ABS plastic.

The cage dipole is a 1/2 wave in size aprox. 125' in length. Each side has 6 wires, held together with galvinized cable clamps,

crimped with a copper sleeve and soldered, then covered with adhesive lined heat shrink. This can be tuned with the end tuning

stubs, to get the lower or higher part of the band.

The 80 meter cage dipole has a bandwidth spread of almost 1 mhz. 3:1 and under.

The 80 meter cage dipole can be installed flat or inverted V, recommened  height 35'.

Remember as with all antennas, be safe and use your head. Stay away from power lines and have a spotter around if you're on

the roof or tower.
