S-Band Dish Antenna System


  Deutsch

Introduction
This is a complete S-band antenna system comprising a 60 cm spun aluminium dish and patch feed, together with all necessary mounting parts.

To this you need to add the S-band pre-amplifier or converter of your choice and you're ready to receive outstanding S-band signals. [2019] The antenna can also be used for transmit, for example to uplink to the Es'hail-2 (QO-100) geostationary satellite.

Contemporary low noise converters only realise their full potential in conjunction with a low noise antenna, and this system offers just that. Lots of gain; low noise; excellent circularity.

A 60 cm (2 ft) system is remarkably small, and can be fitted to a camera tripod. So you can use it portable, from a condo balcony, indoors through a window, as well as conventionally on a mast.

Description
The kit comprises dish, feed support legs, screws and washers, clamps and cable grommet. The 60 cm dish has an f/d ratio of approximately 0.35, and together with the ON6UG/G3RUH patch feed delivers a measured gain of 21 dbic. With the best converters a Sun noise increase of 2.5 db is typical.

The dish is degreased, and drilled for mounting clamps to a boom up to 42 mm (1 5/8") diameter. Dish and feed are unpainted aluminium. Assembly is by six screws for the feed supports, four nuts for the boom clamps, and takes only moments.

Converters
Excellent low-noise converters and preamplifiers are available from:

  • Down East Microwave
  • Kuhne Electronic
  • SSB Electronic USA
