(If this appears correctly) it should be ÂµA but it's quicker to type uA. Answer: UA stands for Urine Analysis.. When you pee in a cup and the doctors take it and analyze it to see if you or whoever has done any drugs or drank any alcohol in the past two weeks. Microamperes. The u is the closest letter many computer keyboards have to the Greek mu symbol.
Do not blind other drivers with your high beam headlights. Dim your lights by switching to low beams before you are 500 feet from a vehicle coming toward you. If you are following another vehicle, change to low beams when you get closer than 300 feet. Use your high beams whenever possible as long as it is not illegal (i.e., in open country when other cars are not near or on dark city streets when no other traffic would be affected by your high beams).
1 For a typical HF station (160 to 10m, 100W), you can use RG-213 if you have something like a tri-band beam, and RG-213 or RG-8X for lower band antennas, up to 100 feet. 2  For longer runs, upgrade to the next quality up of cable. 3  For higher power, use at least RG-213. For a typical 2m station with a 50W transceiver or so, and an outdoor or attic mounted antenna less than 30 feet from the radio, it's OK to use small cable (RG-8X type). 2  If you need a longer run than that, or run higher power, go with larger cable.
