Video transmitter options for on-set video assist, comparing microwave and 2.4 GHz systems
22 years old. Gear and prices may have changed since.
What the thread found
- The Modulus 3000 operates on TV band frequencies and allows reception on any standard TV tuner, making it useful when multiple departments need their own monitors on set.
- Microwave transmitters like those from Coherent and Marell offer rock-solid performance with minimal interference between channels.
- Low-cost 2.4 GHz Chinese transmitters provide a full transmitter-receiver kit for around $300-340 but suffer from signal dropouts when moving, especially around corners or through walls, because the short wavelengths travel in straight lines rather than diffusing around obstacles.
- Upgrading receiver antennas, such as adding a 7-8 dB gain antenna mounted at height, significantly improves range and reliability of 2.4 GHz systems.
- Diversity receiver systems with multiple antennas provide more stable reception than single-antenna setups.
- Handheld monitoring solutions allow directors and other crew to receive video independently of main monitor setups, reducing dependence on a single display.
- Daisy-chaining a TV band transmitter to repeat a microwave signal allows the use of larger antennas on monitors while maintaining coverage across set departments.
Depends on
- 2.4 GHz systems can interfere with WiFi networks in the area, reducing both wireless signals' strength.
- The inexpensive 2.4 GHz transmitters require constant signal input to prevent failure and may fail unexpectedly after extended use.
- Compatibility between some brands (such as Marell and MK-V) appears proprietary, potentially limiting flexibility in mixing equipment from different manufacturers.
- Specific pricing and model availability mentioned reflects early 2000s market conditions.
- No field reports were provided comparing all systems under identical production conditions.
