Satellite LNB engineered for highly stable frequency performance and reliable narrow-band reception. Reduced retuning keeps amateur and professional operators calm during long monitoring sessions. Does the Bullseye QO-100 TCXO LNB deliver the steady, repeatable tuning serious satellite users need?
⚡ At a Glance
- • Frequency Stability: Within 10 kHz in normal outdoor environment
- • Best for: Narrow-band satellite reception, amateur radio operators and small-dish stations
- • Not ideal for: Installations needing multiple independent LNB outputs or integrated multiswitches
TCXO control keeps frequency drift low and repeatable, aiding long monitoring sessions. Factory calibration to within 1 kHz plus a 25 MHz reference output supports precise frequency locking.
Reliable frequency lock - with TCXO and factory calibration
Temperature-compensated crystal oscillator reduces thermal drift, maintaining stability within 10 kHz in typical outdoor conditions. Factory calibration refines the centre frequency to within 1 kHz using GPS-locked spectrum analysers.
Long listening sessions remain centred on narrow-band signals without frequent retuning. Suitable for users who need steady frequency lock for telemetry or narrowband transponders.
Precise referencing - with 25 MHz output on secondary F-connector
A dedicated secondary F-connector provides a 25 MHz reference output that can be used to discipline external local oscillators. The reference allows connected equipment to achieve tighter frequency alignment.
External receivers or reference-capable hardware can lock to an accurate 25 MHz source for repeatable tuning. Helpful when sub-kilohertz stability is required over extended periods.
Good small-dish performance - with wide input and output coverage
Input coverage spans 10489 - 12750 MHz, with L-band outputs of 739 - 1950 MHz (low) and 1100 - 2150 MHz (high). Single universal output design converts Ku-band signals to receiver-friendly L-band ranges.
Delivers reliable reception even on modest dish sizes, according to user feedback. Straightforward single-output cabling keeps installations simple and compact.
