You can put down the Bird43 all you want, but check nearly every

You can always use an A range Bird slug (25 to 60 MHz) on the upper end of the

When taking reflected power readings the slug should be 1/10 of the
forward slug value when testing a reasonably good antenna. So, a 100
watt forward slug would require a 10 watt reverse slug for reasonable
accuracy.
Unfortunately, the smallest HF slug Bird make is 25 Watts. That means

I spoke to someone at Bird (when they were really Bird) years ago and I
was told that the Bird wattmeter is accurate to ±5% of top scale. This
means that a 100 watt slug can be off ±5 watts _anywhere_ on the meter.
So, a transmitter emitting 50 watts out, using the Bird and a 100 watt
slug,
There are a lot of used Flukes on EBay, maybe not the latest model, but for

Another way to look at that percentage of full scale is to consider a

A DVM has relatively high input impedance and will pick up stray 60 Hz

One of the characteristics I look for is response time / refresh time /
time to read. It is much easier to make adjustments that depend on
measured voltage or resistance if the meter quicks refreshes the
