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 AND HORIZONTAL ANTENNAS
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.
BOLT PANEL ANTENNA V.4
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.
