Icom Mobile Antennas for Shortwave

Icom AH-760


Automatic Antenna 1.6 - 30 MHz

The Icom AH-760 is a motor tuned antenna with a total length of 2.5m and 200W PEP max. power handling. The 84m high base unit contains the motor and electronics, and on top of this unit the approx. 1.5m long whip is installed with a spring. This antenna covers the entire HF range from 1.6 to 30 MHz. In contrast to ther so called 'screwdriver' antennas which use a DC motor, this antenna uses a powerful stepper motor which drives a cam belt. This allows a much faster tuning of the resonance of the antenna. When tuned from memeory the tuning usually takes less than 0.5 sec!

For automated operation with all Icom transceivers which have a TUNER socket, a control cable (OPC-2321) is available optionally. But this antenna can be operated entirely without an interface cable - just transmit with low power. The antenna is manufacturer following MIL-STD 810G, it is waterproof according to IP 68 protection. Of course this antenna can not only be used on vehicles, but also at fixedd locations where a proper ground radial network is provided. For installation th AH-760 has a solid M16 bolt at the bottom. Various mounting holders are available.

The optional NVIS kit AH-5NV can be used for better sky radiation at lower frequencies. The use of this option limits the frequency range of the AH-760 to 1.6 to 16 MHz.

Icom AH-740


Automatic Aantenna 2.5 - 30 MHz

The Icom AH-740 is a compact automatic antenna for the frequency range from 2.5 to 30 MHz, for use on a vehicle or for stationary use (with proper radials). The length with the whip is just 191cm. In contrast to the larger AH-760 (see above) the AH-740 is tuned with relays which select the required inductors to achieve a match in very short time. The SWR is usually 1.5:1 or better. Optionally the NVIS Kit AH-5NV is available, which extendes the frequency range at the lower end to 2.2 MHz.

Accessories

Icom AH-5NV NVIS Kit


This NVIS kit was developed to replace the standard radiator whip of the AH-760 or AH-740 antenna or as a stand.alone radiator when used with another tuner. The standard radiator can be carried in the vehicle as a backup antenna.

This radiator is manufactuirer from highest quality maeterials. Coated glassfibre radiators, a solid copper mesh, machine milled stainless steel and anodized aluminium are use to construct a robust and long lasting antenna. The NVIS kit contains all materials required for installation on a vehicle, for example with the included triple magnet base.

The NVIS kit AH-5NV improves the gain of the antenna by 5 to 8 dB. The tuining range changes, depending on antenna, see table above. As the name implies this klit improves near vertical sky rqadiation, which is crucial for short to medium range communuication in difficult terrain. If previously there was a dead zone between the ground wave and sky wave, the NVIS kit improves communication over short to medium distances (20-500km, see diagrams).
