LMT1/LMR1
VHF Narrow Band FM Low Cost multi channel radio modules
The LMT1 transmitter and LMR1
receiver modules offer a multi channel,
low power, and reliable VHF data link.
This makes the LMT1/LMR1 pair ideally
suited to those low power applications
where existing wideband modules have
insufficient range, or where low cost
multi-channel operation is needed
without
compromising
on
RF
specification or regulatory requirement.
