We have revised the tried-and-tested design of the active antenna, which dates back to our early days, eliminating design weaknesses and realizing the customer’s primary wish for even better performance. The new Active Diapason High Gain series has a doubled native antenna gain, optimized matching to the downstream amplifier, an improved noise figure and, last but not least, a waterproof N-jack mounted in our proven drip shield.
The most important properties
- This antenna can be used outdoors.
- Not suitable for broadcasting purposes.
- Ideal for stationary Mode-S/ADS-B reception
- Optimized for DVB-T or SDR-based receivers
- Compensation of long cable losses (up to 50 m of CO100AF or 30m RG58)
- Amplification of weak signals
- Rejection of GSM frequencies (-35 dB)
- Significant improvement of reception range (compared to standard DVB-T antennas)
- Protected antenna connection (N socket)
- Please note: when using low loss setups the high gain of this antenna may lead to an overload of the DVB-T dongle’s RF input stage. Very short cables may lead to deterioration of reception quality.
