Ranger units require the use of external antennas for basic operation. For Ranger, we recommend ONLY using a Horizontal + Vertical (H+V) antenna configuration.
Vertical (V) antennas are ideal for achieving diversity indoors and offer good performance in a wide variety of short-to-medium range situations when quick setup and flexibility are key. Once you move outdoors with the V antennas, the RF signals travel in a similar or identical manner toward 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 perpendicularly 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.
If using the Bolt Panel Antenna V.4 with your Ranger 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.
