This guy has a list of them,

Give him a shout and tell him what your looking for, he'll be happy to help you out. Don't forget to include your callsign and a copy of your original post.

Well to satiate your curiousity let me tell you that there  are radios that with a simple modification will do what you've asked..... illegaly of course.

David,
If you could provide an email address I would be happy to contact you offline and steer you to the right "build it yourself" group within the Federal LE community. They will have regular meetings, organized classes and great networking in your region. This LE group helps others at exactly what you wish to accomplish. I will also send you info on sources, schematics, and how to modify COTS equipment, etc.

 As a Federal employee doing Federal business you needn't be too concerned with the FCC in "some" of your undertakings as you are not governed by the FCC, but by NTIA. This LE group will explain it all to you however.

Charles,
License plate antennas have their place on rolling surveillance vehicles that are pumping 50-100 watts into them and communicating simplex to other vehicles that are within a few miles of each other. Body wire surveillance requires a different antenna configuration to minimize drop outs and lost signals, especially since every word and nuance must be heard and interpreted for officer safety.

I explained it in my previous post but will do so again.

When your sitting 2 blocks away from your "wired" subject who's inside a building and your antenna is 12" off the ground and at the far end of your vehicle with another vehicle parked 8" of your bumber, well that's just not the best or safest place to receive a weak signal.  

Stay away from gimmicky antennas that have poor radiation characteristics like license plate antennas, side mirror antennas etc. The bottom line is this.... A body wire is a LIFE and DEATH device used under very difficult conditions and environments. It's a low power device less than a watt and usually around 100-200 mW.... and that's on a fresh battery. Just wait 15 minutes and THEN see what it's putting out.

All this requires you to have the best antenna you can as high and clear of obstacles as the situation will allow.  If you can't disguise an antenna on the roof or fender, then using thin wire and RG-174/U make an inverted V antenna on a wooden or plastic coathanger and hang it in the window closest to your U/C operator. The coax leaves the coathanger from the hook portion and runs along the trim and then down a doorpost to the receiver. You can also put a T shirt or nylon jacket over the hanger if you have to drop the coax straight down.

My advice comes from lots of experience in this area.

Here's the gov't test results.

"Lifetime" can mean many things. Your lifetime (birth to death), Lifetime warranty.... Hey Goodyear, I bought these tires back in 1965 with a lifetime warranty, I'm still alive and these old tires are worn out.  You owe me a new set of tires.  Congress passed a bill in 1907 and abolished it in 1934, it had a life of only 27 years.  The judge gave him life in prison when he was only 20 years old, of course in this state, life means 25 years so he'll be out when he's 45.
  It's all in the interpretation. It doesn't necessarily mean a human lifetime.

I say it is legal. You can call yourself anything you want on cb, whether it's your "handle", a nickname, a unit number, the name of your favorite superhero, the Queen of England, George Bush, Air Force One, your real name or even your ham callsign. As long as the cb equipment is FCC approved for 11 meters, that's all the FCC cares about (if that even). You don't need a "valid" identifier to key the mic on a cb. Any name or number, real or imagined is FB.  

Forget your schematic. Go to minicircuits.com and look at the ERA-5 mmic. Don't forget to add a few poles of Low Pass filtering as this device is spec'd to over 4 Ghz. You wouldn't want any harmonics amplified.

Full 800 mhz receive coverage is legal everywhere except in the United States. That being said, it would require you to to disable the local oscillator synthesizer and inject your own synthesized L.O. frequencies. The reason being that the cellphones internal frequency tables are burned in at the factory, usually into a custom i.c. Unless you know all the divide by ratios of the synthesizer and are able to code that up and burn it into a new chip you might as well build your own synthesizer. Is it worth the cost? No, it's cheaper to buy a $150 scanner with full cell coverage.

<<Transmit end uses "the Comet GP-9 is a 2m/70cm dual band vertical base antenna. band coverage 144–148, 442–450 MH ">>

Your transmitter occupies a bandwidth from 436 to 442 Mhz. Your Tx antenna doesn't even cover this range. Your antenna should have no more than a 1.5:1 VSWR over this 6 Mhz bandwidth. This may be part of your problem.
