Model comparison

Three lengths with an M6 threaded connection

GL400S, GL400SI and GL400SII are vertically polarized mobile antennas with an M6 threaded connection. Each source identifies an M80 magnetic-mount match and a customizable cable connector.

The listed lengths increase from 30 cm on GL400S to 60 cm on GL400SI and 80 cm on GL400SII. Their respective gains are 3.2, 3.6 and 5 dBi, while maximum power is 100 W for all three.

The sheets list 16 MHz bandwidth for each model. GL400S and GL400SI specify 400-480 MHz; GL400SII specifies 400-490 MHz. The comparison preserves the individual VSWR limits and weights.
