10w 30dB SMA attenuator:




I picked this up to use with a cheesy little UHF watt-meter. It's just a board with an LCD on it, and is made
to be used with an attenuator since it's very low power. You enter the value of the attenuator and the board
does the math and displays watts, dBm, dBv, etc. despite being low power itself, it's pretty high precision,
so it can still get a reading well into the milliwatts on a 5 watt HT. Much better than any of my larger meters
that struggle to provide a useful reading on an HT on low power (at 100mW) where the bigger meters can barely
even move their needle.
