HFw2.02 High Quality Antenna Cable



Giovannini HFW2.02 is the best wire for antennas: Quad, delta loop, dipole, wire beam, long-wire, HF receiving antenna, beverage, wire log-periodic, V beam, rhombic ...

Low loss RF-conductivity. Low weight and low wind load.


HFW2.02 braid wire is built on a stainless steel core with 1.5mm Ø (0.059 Inch). This core is covered with a silver plated copper mesh. Because of the steel core the wire has a very high tensile strength, sufficient to raise long dipoles or beverages very tautly. The silver-plated copper mesh on the outside results in a very good conductivity, good for high currents as they are present at the center of a dipole.



Specifications:
- Ø 3.0 mm ( 0.115 Inch) PVC Jacket UV resistant
- Ø 2.1 mm ( 0.083 Inch) Silver plated copper braid ( 19 steps)
- Ø 1.5 mm ( 0.059 Inch) 49 x 0.18 stainless steel core AISI 316 ( UNI X 8 CrNiMo 1712 – UNI 6900/71)
- Up to 12 KW RF , 1.5 to 30 MHz
- Temperature range: - 100 to + 155 deg C
- Weight : 21.85 g/m ( 0.0146 lbs/ft)
- DC resistance: 30 Ohms/Km
- RAL 7001
- Breaking load 1170 N ( 257 lbs)

HF Broad Band Wire Antennas

HF broadband antennas for tactical and fixed use, broad-band dipole and rhombic antennas.

  • Mod. D2T-M
    HF/VHF directional antenna, 1.5-200 MHz

    COMPACT ANTENNA SYSTEM FOR TACTICAL AND FIXED USE
    SMALL SIZE - IDEAL FOR RESTRICTED SPACES
    HF Compact and light directional antenna suitable for operation covering medium to long distances.
    Used for the transmission and reception of horizontally polarized signals. Frequency range: 1.5 - 200 MHz

    • 1.5 - 200MHz CONTINUOUS COVERAGE
    • NO TUNING REQUIRED
    • USES ONLY ONE 50 OHM COAXIAL CABLE
    • BOOM: 2m (6.6ft)
    • ELEMENTS: 6m (19.8ft)
    • WEIGHT: 6kg (13lb)

    The D2T is a non-resonant high-impedence antenna, composed of two folded dipoles dephased by 180°. It has a non-inductive terminating resistor and broadband RF transformer fed with a single 50 Ohm cable. The D2T is bi-directional starting from about 10MHz with 10dB F/S. At 21MHz it gains 3dB with 5dB F/B and 10dB F/S, and progressively it reaches 6dB at 30MHz with 5dB F/B and 20dB F/S. At VHF it shows a daisy-type radiation lobe. Up to about 15MHz both the transmitted and received signals are attenuated (see the ‘Yield’ graph).
