Cb Two Way Handheld Radio

I'm looking for a CB radio with industrial professional radio quality, if anyone has used a professional motorola two way handheld radio you know how durable they are. I had a Cobra HH 38 WX ST and it broke when it fell off my belt. One thing I'm looking for is a spring loaded pocket clip like the pro radios have, they hold the radio on your belt much better than what the Cobra did. All in all the radio was good but it only lasted a few weeks before it fell off my belt and smashed.

So my question is...is there such thing as a professional quality handheld CB radio out there?

I have never seen a durable CB radio, and I operated a radio repair shop for 24 years.

I have had all types of cb's, I want one that I can program the channels and not have them preset. I am an EMT and want the ability to program the channels to my own unit not owned by the company.. I understand not being allowed to have access to the swat channels but I want to have all of the others ranging from 20-25mhz up to the150mhz- 300mhz channels. We can buy scanners that will listen to them why or what and how do I need to list it on google or wny search engine...??

Radio Shack sells hand-held scanners that will receive almost all frequencies. Or just google hand-held scanner. Many police channels are digital now, so you would have to see if there are digital capable hand-held scanners. I don't think it would be a good idea to get a radio that you could transmit on. You would need written permission to transmit on another agencies frequency. Without this, you could face legal action.

Why are handheld radios(FRS, CB, Amateur) antennas just one wire? How can that work to receive and transmit if it’s just one wire? I mean the antenna should be TWO wires, just like the antennas on the big stations, or the TV antennas. It should be a closed circuit((- and +) OR (- and ground)?).

That brings me to my next question:
I have a FRS radio. I used a TV antenna cable, and connected the radio wire to the inside wire of the cable. The cable goes up to my roof, which is only about 40 feet high, but did not work at all. If I go to the top of the roof with the radio on my hand the reception/transmission is great, HOW CAN I EXTEND THE SHORT FRS ANTENNA TO THE ROOF IN AN EFFECTIVE WAY, JUST LIKE IF I WAS UP ON THE ROOF WITH THE RADIO ON MY HAND???

They do have 2 wires. Internally to the radio there is a ground.

Now for you next question:
buy your self a Discone antenna and a good quality 50ohm coax
You need to adjust you SWR . You also need to know what band you are on. You can find that out by going to the manufactures wed site
If your house is aluminan sided that will cut down on you reception/transmission. When your standing on the roof you are outside of the box (so to speak) so the siding isn't causing the problem.Mount the antenna on the chimney and set your SWR.
this should help.

Good luck

FRS radios are not allowed to have external antennas, and their maximum power is limited to half a watt.
A GMRS radio is identical to an FRS radio - it uses the same frequencies. But it might have two important differences.

The first difference is that it might be higher powered than the FRS radio. extra power does not always automatically mean extra range, so don't be too excited by the extra power that a GMRS radio offers. All that extra power really means is your batteries won't last as long!!!

The second difference is that the GMRS radio can have an external antenna.Generally it seems that manufacturers claim an 'up to 2 mile' range for FRS radios and an 'up to 5-7 mile' range for GMRS radios (with built in antennas) and then claim 'boosts range by up to 75%' for an external antenna add-on. So, this would suggest a best case range of about 12.25 miles for a moderately low powered GMRS radio with a 'normal' non-directional antenna.

The dipole antenna is simply two wires pointed in opposite directions arranged either horizontally or vertically, with one end of each wire connected to the radio and the other end hanging free in space. Since this is the simplest practical antenna, it is also used as reference model for other antennas; gain with respect to a dipole is labeled as dBd. Generally, the dipole is considered to be omnidirectional in the plane perpendicular to the axis of the antenna, but it has deep nulls in the directions of the axis. Variations of the dipole include the folded dipole, the half wave antenna, the groundplane antenna, the whip, and the J-pole.
The Yagi-Uda antenna is a directional variation of the dipole with parasitic elements added with functionality similar to adding a reflector and lenses (directors) to focus a filament lightbulb.
Loop antennas have a continuous conducting path leading from one conductor of a two-wire transmission line to the other conductor. "Symmetric" loop antennas have a plane of symmetry running along the feed and through the loop. "Planar" loop antennas lie in a single plane which also contains the conductors of the feed. "Three-dimensional" loop antennas have wire which runs in all of the x,y, and z directions. By definition they are not planar. They may, however, be symmetric about planes which contain the feed.
The (large) loop antenna is similar to a dipole, except that the ends of the dipole are connected to form a circle, triangle (delta loop antenna) or square. Typically a loop is a multiple of a half or full wavelength in circumference. A circular loop gets higher gain (about 10%) than the other forms of large loop antenna, as gain of this antenna is directly proportional to the area enclosed by the loop, but circles can be hard to support in a flexible wire, making squares and triangles much more popular. Large loop antennas are more immune to localized noise partly due to lack of a need for a groundplane. The large loop has its strongest signal in the plane of the loop, and nulls in the axis perpendicular to the plane of the loop.
The small loop antenna, also called the magnetic loop antenna is a loop of wire (in other words, both ends of the wire connect to the radio) less than a wavelength in circumference. Typically, the circumference is less than 1/10 for a receiving loop, and less than 1/4 for a transmitting loop. Unlike nearly all other antennas in this list, this antenna detects the magnetic component of the electromagnetic wave. As such, it is less sensitive to near field electric noise when properly shielded. The received voltage can be greatly increased by bringing the loop into resonance with a tuning capacitor. The small loop has a maximum output when the magnetic field is normal to the plane of the loop, and since this field is transverse to the direction of the wave, has a maximum in the plane of the loop. This is the same mechanism as the large loop.
The electrically short antenna is an open-end wire far less than 1/4 wavelength in length - in other words only one end of the antenna is connected to the radio, and the other end is hanging free in space. Unlike nearly all other antennas in this list, this antenna detects only the electric field of the wave instead of the electromagnetic field - think of the free end of the wire as measuring the voltage of that point in space, as opposed to measuring both the voltage and the magnetic field. Its receiving aperture cannot be changed by adding lumped components, but more efficient power transfer can be achieved by impedance matching with such circuits. Electrically short antennas are typically used where operating wavelength is large and space is limited, e.g. for mobile transceivers operating at long wavelengths.
The parabolic antenna is a special antenna where a reflector dish is used to focus the signal from a directional antenna feeder. Antennas of this type are commonly found as Satellite television antennas, Wi-fi / WLAN, radio astronomy, radio-links, mobile phone backhaul and military tactical radio link -antennas. They are characterized by high directionality and gain but can only be used at UHF to microwave and higher frequencies due to dimensions getting too large at lower frequencies.
