Product Description

The VSWR LED bar signals the tuning of the antenna. The standing wave ratio should be
better than 1:2, and there should be only green or at least orange LED lights active. Tab. 6
lists the LED colors.
VSWR LEDs Color Value
(VSWR)
Quality of Standing Wave Ratio
LED V1 green 1 optimal
LED V2 green 1,2 very good
LED V3 orange 1,5 good
LED V4 orange 1,7 still acceptable
LED V5 red 2 poor, reading efficiency reduced. Antenna
needs to be tuned
LED V6 red 2,5 poor, reading efficiency reduced. Antenna
needs to be tuned
LED V7 red 3 poor, reading efficiency reduced. Antenna
needs to be tuned
LED V8 red INF poor, reading efficiency reduced. Antenna
needs to be tuned
