Product description I operate HF amateur radio — can this meter measure SWR and power on 40m, 20m, and 10m bands? Yes, the SW-28HF covers 1.5-60 MHz, which includes the 40m (7 MHz), 20m (14 MHz), and 10m (28 MHz) amateur radio bands. It measures forward power, reflected power, and VSWR across this HF range. What is the maximum power rating — I run 100W on my HF transceiver? The SW-28HF is rated for 120W maximum input. A 100W HF transceiver is within this rated capacity. Always verify your radio's output level before connecting to avoid potential meter damage. This is an HF meter — will it also work on VHF or UHF frequencies for occasional use? No, the SW-28HF is designed for 1.5-60 MHz HF frequencies only. It does not support VHF or UHF bands. For VHF/UHF measurements, a separate meter designed for the 125-525 MHz range is needed. Does this meter require external power, or does it operate passively from the RF signal? The SW-28HF operates passively using the RF signal being measured for display illumination. No external power supply or batteries are required for basic SWR and power measurement operation. The meter has a digital display — does it show SWR and power at the same time? Yes, the SW-28HF features a digital LCD display that shows forward power, reflected power, and VSWR readings. Refer to the product listing or manual for the exact display layout and measurement modes available.
