**** off, then don't come back.
Scalable, true diversity receivers, idiot!
In four ranges: Baseband, Standard broadcast UHF TV band, 900MHz,
2.5 GHz, and custom for the military. Voice, video, and serial data
links.
Do you even know what a "panel" configuration is? It's a clad PCB
design with a dielectric foam backing sheet.
Also, ruggedized transceivers across the same bands. Used at race
tracks, movie sets, etc. Even have a special in use on a carrier deck
with a DVR going on it.
Idiot. I wasn't talking about the topic, I was responding to the
OTHER TWIT's claim that I didn't do the work by stating what work I
did. It has NOTHING to do with the original thread topic, retard.
You're an idiot.
We noticed it had nothing to do with the thread.... What's new?
When you do that work, is it janitorial or are you in the mail-room?
I'm observant.

You're a fucking retard. You prove that every time you post
horseshit like this.
No... You're an idiot.
I apologize. So you are a grounds keeper?
So where's the depth?
Oh goodness. Radar works by time division multiplexing transmit andAnthony said:It's way simpler than that.
Everything is happening at the same time usually (full duplex). First
off,
the transmitter and receiver are on different frequencies. This is
usually not enough to prevent the transmitter from overloading the
receiver, so
careful filtering prevents the transmitter from getting in. Google
"antenna duplexer".
When it comes to antennas, you're not too far off. ;-)
Oh goodness. Radar works by time division multiplexing transmit and
receive. Cell phones do so to a lesser extent and add band split, the
transmit frequencies a about 20 MHz apart. Older systems like the very
earliest radio data networks (google Aloha network, University of Hawaii)
all the transmitters and receivers were on the same frequency and time
shared (like a condo time share) transmit time. Depending on the case
involved code division multiplexing is also used. This allows multiple
transmitters to transmit at the same time on the same frequency and still
have each transmitters signal to be independently received. This is used
in GPS. Please try googling TDMA, FDMA, and CDMA; which stand for time,
frequency, and code, division multiple access. Please also check out
devices called circulators, 3 port and 4 port. All of the things make
sharing a single antenna much easier.
