4G-CAB-LMR240-50 TNC(m)-RA to TNC(f)-STR
LMR-240, 50 foot RF cable
Type: Plenum
Note: The cable is not recommended for longer distance links due to high
loss of 50 foot LMR240 at most cellular frequencies. The customer may need
to do a site survey to validate whether the cable allows sufficient
signal-to-noise ratio to or from cell tower.

3.1dB @ 1.7 GHz
3.8dB @ 2.4 GHz
4G-CAB-LMR240-75 TNC(m)-RA to TNC(f)-STR
LMR-240, 75 foot RF cable
Type: Plenum
Note: The cable is not recommended for high throughput or longer distance
links due to high loss of 75 foot LMR240 at most cellular frequencies. The
customer may need to do a site survey to validate whether the cable allows
sufficient signal-to-noise ratio to or from cell tower.
