I use this - Phenyx Pro Wireless Microphone System, Dual Mic Set with Handheld/Bodypack/Lapel Mics,2x100 UHF Channels,328ft Range (PTU-71-1H1B).
$149 on Amazon

Thanks for this suggestion, Jeff. I took a chance and ordered one, and Iím pleasantly surprised. It doesnít sound good (of course), but as an announcer mic and talkback mic, it will be fine.  Initial test had zero dropouts at 150-200í, which is good enough for my purposes. The only odd thing about it is that the board meters show a tickle on those channels even when the mic is muted, but turning off the gate on that channel I canít really hear anything over and above the system noise when I toggle the mute. I wonder if itís pushing some ultrasonic into the output or something, which the board registers but doesnít reproduce. 

Anyway, thank you!

My card key for the office door doesn't work beyond a few millimeters  ;)

Would they be amplifiers?

Weigand effect sends out a field, that field excited the coils that disgorge their data.

I canít see how the field range could be extended and I think it would have to be on the data side.

You know how it works?

No, I don't know the details of how it works. But there's a reason they sell wallets with RF shields now.

That's RFID different tech that Weigand.  All sorts of fun toys out there.

another piece of gear to help.  i started to work with SDR  software defined radio.   using a computer and a usb dongle to connect an antenna too.  allows me to see spectrum for the radio frequency and noise floor.   nooelec is the dongle.  cost was around 50 dollars.  i also purchased several old vhf mics from ev and audio technica to use for my system.
