Moonraker SWR-777 Digital Wattmeters provide information about the state of your antenna at a glance. A color display shows the forward power as well as the current SWR and battery voltage. The color display provides a number of display options that can provide up to the minute information as to the current state of your antenna system performance. Three LED lights provide visual indication of the SWR status: the left (yellow) LED is below 1.5:1, the middle (green) LED indicates an SWR between 1.5-2.5:1, and the right (red) LED indicates that the SWR is over 2.5:1; an audible alert can also be enabled. Three buttons also are featured on the front panel; these are used to change settings on the meter. Other configurable options allow the user to adjust the meter display if they have compared the readings of the meter with a calibrated meter. The rear panel features a master power switch, two SO-239 jacks (one for the transmitter and one for the antenna) and a USB-C port for power.

Covering a frequency range of 1.8 to 250 MHz and operating with a maximum power rating of 210 watts, this meter will cover the needs of most operators. This compact meter, measuring in at 3.46 in. x 2.48 in. x 1.50 in. and weighing just 6.63 ounces, is sized for use in the shack or, with its 3.7V, 1000mAh internal battery, can be used portable as well.
