Graphics 1090MHz Antenna

Especially for the reception of the ADS-B/Mode-S aircraft beacon we are offerign this special antenna. The antenna is protected and weatherproof with a solid glassfibre tube and comes complete with clamps for mast mount. Wall mount is also possible.

This antenna is a narrow band design for secondfary radar (IFF) from 1070 to 1110 MHz. Due to the omnidirectional characteristic and the medium gain the reception is good in any direction, also up. Cable not included.

Technical Data
  • Gain: 5 dB ±0.5dB
  • Length: ca. 53cm incl. mast clamp
  • Weight: ca. 700g
  • For mast diameter from 30 to 50mm
  • Connector: N female

AS-1090 Pre-Amplifier for 1090MHz

Pre amp AS-1090 AS-1090

The AS-1090 is a pre amplifier designed specially for the Virtual Radar receivers SBS-3 and Radarbox. With such an amplifier the reception range of the SBS-3 is considerably extended. The AS-1090 can be used with any passive antenna like the GP-1090 or a discone antenna.

An antenna pre-amp should always be mounted as close to the antenna as possible, not at the end of the (long) cable. If the pre-amp is used at the end of the cable (downstairs) it will still amplify the signal, but also the noise added by the cable. This results in a worse signal to noise ratio (SNR) and thereby in less effective decoding of signals. Another advantage of using the pre-amp right at the antenna is that you can use cheaper cable with higher attenuation for the long downlead to your shack.

  • Technical Data
  • Frequencyrange 1030 - 1090MHz
  • Gain 12dB
  • Noise figure 0.9dB
  • Supply voltage 12VDC over coax (remote)
  • Power consumption 100mA
  • Max. Input level +2dBm
  • Connectors 2x N female
  • Size 74 x 93 45 mm
  • Weatherproof case for mast mount

The AS-1090 includes all mounting hardware for mast mount. A Bias-T (DC injector) is not included.

AS-1090BT DC Injector

To supply the AS-1090 pre-amp with power the 12V DC voltage is injected over the coaxial cable. This requires a DC injector (Bias-T) at the receiver (downstairs). A suitable Bias-T is the AS-1090BT. The AS-1090BT offers one N female connector (to antenna) and one BNC female connector to SBS-3 and a connector for 12VDC.

Cables for GP-1090 Antenna

With a good cable ou can save a lot of hassle, and you improve the reception! The traditional cables used for scanners etc. (RG-58) ar not suitable for these high frequencies, here you should use a good low loss coaxial cable. like Ecoflex-10, Aircom+ or even Ecoflex-15.

Depending on if a pre-amplifier is used or not, you either need one or three cables:

With pre amplifier:

  1. Short cable with 2x N male connector between antenna and pre-amp
  2. Long cable with 2x N male from pre-amp to Bias-T
  3. Short cable BNC/SMA from Bias-T to receiver

Without pre-amplifier:

  1. Long cable with N male and SMA male connector from antenna to receiver
