40 meter cage dipole - used at W1AW. Each cage dipole is hand made with quality and care, using materials that will take the abuse of even the most harsh environment. The wire used is #14 AWG 7 STRAND Copper Hard Drawn with. 030 High Density PE Black Jacket.
Making this an excellent choice for antenna wire! Will not stretch over time as would a wire that is not hard drawn.
The center connector used is the W2DU ANsulator , W2DU End-sulators. The balun used is the Choke-Kit.Frequency: 1.8 - 60 MHz. Through-line impedance: 50 ohms (nominal). Insertion loss: less than 0.2 dB at 60 MHz. Common mode inductance: 24 uH (nominal).
Load mismatch tolerance: greater than 5:1 VSWR at 2kw. Ferrite material: seven Fair-Rite P/N 2643102002 (850 Initial Perm, 2900 gauss at 10 oersteds, nickel-zinc).
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). For a full explanation on how a balun works, see Chapter 9 of Transmission Line Transformers by Jerry Sevick, ISBN 1-884932-18-5. The cage material is 7" round X 1/4" thick white ABS plastic.The cage dipole is a 1/2 wave in size aprox. Each side has 6 wires, held together with galvanized cable clamps, crimped with a copper sleeve and soldered, then covered with adhesive lined heat shrink. The 40 meter cage dipole has a bandwidth spread of almost 1 mhz.
The 40 meter cage dipole can be installed flat or inverted V, recommended height 25'. I did preform a test at center 12 feet off the ground, ends at 7 feet and it went flat 1:1 swr. The higher i went into the air the wider the bandwidth became. 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.
