| Jul 21, 2020 at 18:38 | comment | added | Frank | @Andyaka I'll be using public safety bands in UHF and VHF. 150 -170 MHz, 470-512MHz. | |
| Jul 21, 2020 at 7:20 | comment | added | Andy aka | VHF top limit is 300 MHz - have you fully specified the full usage spectrum? | |
| Jul 20, 2020 at 22:54 | comment | added | Frank | @MarcusMüller That's a good point. Actually these are for multiple purposes. For direct transmit to units in the field, but also to mountain top repeaters. But, this gives me something else to consider. | |
| Jul 20, 2020 at 22:53 | comment | added | Frank | @Andyaka sorry that was a typo. Supposed to mean it operates in VHF, UHF, and 700 - 900 Mhz frequencies. | |
