Thanks for all of the replies.
I just ordered a used Bird 43 and an 801-1 1W 800-1000Mhz element.
from radiodan.

Uh-oh!! You're in trouble now. As a recovering Bird addict, I must warn
you that YOU CAN'T OWN JUST ONE BIRD SLUG.

You ordered a 1-watt 800-1,000 Mhz element and you think you're safe. No
way. You will notice that the Bird carrying case has room for several
slugs, so why not fill it up? So, you'll figure, oh, what the hell, I
really need a 1KW HF slug. Then comes a 1-watt HF slug. Then maybe you'll
need a 100-watt VHF slug. And from that point on, it's all downhill into
the dark night of addiction.

Then your wife says, "Why do you need all these?" And you say something
like, "Well, I have half as many slugs as you have shoes so what's the
problem."

Get help, quick!!!

I know.

Or you could get back to basics. Buy a used directional coupler off of eBay.
Measure power forward & reverse, and do the simple math.

Or get even further back to basics and MAKE a directional coupler.
It's not all that difficult, and not bad to check for directionality.
RFSim99 has a tool for designing microstrip and other couplers (though
it fails to tell you that for the given coupling, the microstrip lines
should be coupled for a quarter wave distance). Hint: people who
manufacture equipment that operates in the GHz region often put
couplers right on the PC boards--biggest cost is a bit of real estate.

Cheers,
Tom

Or rip one out of a defunct cell phone.
