The length of a whip antenna is determined by ...
Much of the site is devoted to the enormous overhead wire antenna array that is necessary to efficiently radiate the VLF waves. The antenna, shown above, consists of ten catenary cables, 5,640–8,700 ft (1,719–2,652 m, 1.1–1.6 miles) long, suspended in a zigzag pattern over the valley between Wheeler mountain and Blue mountain on twelve 200 ft. towers on the mountains' crests.
Antenna connector: BNC female with threaded collar, 50 Ω characteristic impedance, unbalanced [10] Antenna Tuning Capability: OE-505 10-foot (3 m) whip, RF-1941 dipole, random wires, long wires [10] Data Interface: USB and Ethernet with adapter [10] GPS: Internal antenna, with external antenna connector.
An antenna top cap installed on the tip of the antenna provides protection for personnel. The construction is the same as is used for sectional fishing poles. The base has a male 3/8-24 thread which is the same as is used on most ham radio and CB antennas. The antenna was 9 feet long when fully assembled.
The radar utilizes a 12-foot (4 m) parabolic antenna giving a beamwidth of 1.2 degrees at the half-power points. The range system uses 1.0, 0.5, or 0.25-microsecond wide pulses. Pulse width and prf can be set by pushbuttons.
