Mounting

Updated

Bolt 4K transmitters and receivers require the use of external antennas for basic operation. Different conditions will determine the type, orientation, and placement of the antennas.  

VERTICAL AND HORIZONTAL ANTENNAS

Vertical (V) antennas are included as a standard item with your Bolt 4K, offering  good performance in a wide variety of short-to-medium range situations when quick setup and flexibility is key. V antennas are ideal for achieving diversity indoors. Once you move outdoors with the V antennas, the RF signals travel in a similar or identical manner towards the receiver, weakening diversity. Horizontal (H) antennas were designed for use with the V antennas. H antennas cause the RF signal from the transmitter to propagate in a perpendicular manner compared to the vertical signal from the V antenna. The H+V antenna configuration helps to maintain the quality and performance of your video  transmission, especially when your signal would otherwise begin to deteriorate due to noise and/or longer ranges. NOTE: H+V antennas must be attached to both the transmitter and receiver.

For most setups, the ideal position for the four TX antennas and the five RX antennas  is perpendicular to the ground/horizontal plane so that they point straight up and down. If the transmitter is mounted at an angle or on its side, the antennas must  also be arranged so that they point up. Pointing the antennas in any other direction re-orients the radiation pattern and may reduce performance.

BOLT PANEL ANTENNA V.4

If using the Bolt Panel Antenna V.4 with your Bolt 4K/4K LT 1500 or MAX receiver, you must connect the five RP-SMA connectors from the receiver to the back of the antenna (see below for connector placement), and position the antenna so that the front (with the Teradek logo) has a clear line of sight to the transmitter.  

The Bolt Panel Antenna includes an omnidirectional antenna with a receive pattern that varies based on its distance from the transmitter. The horizontal receive angle measures 55° at 5,000 ft (1.5 km), 104° at 4,000 ft (1.25 km), and is effectively omni-directional at up to 500 ft (150 m). The vertical receive angle measures 20° at any distance. In order to maintain signal strength, you need to adjust the height of the receiver and/or the height of the transmitter accordingly so that there is no more than 20% obstruction.
