Would this work well for receiving out of band (i.e. for a police/fire/aircraft scanner, specifically a SDR USB receiver)?

John, this is primarily designed for Amateur radio TRANSMITTING. So it's at best efficient at the frequencies it's designed for. Will it work on higher frequencies? Yes it just will not be as well tuned for higher freq. You should be able to hear local PS stations.

Most police, fire and aircraft are within range, not exactly sure what a SDR USB receiver is. However, where I use it more is just above 470mhz. SWR is 1.1 I can tx and rec from my repeater which is 48 miles and on the opposite side of a hill with normally no issues. Hope this was helpful

Yes.... A reciever is far more forgiving about bandwidth than a transmitter is. I checked the VSWR of my Tram dual band antenna and its bandwidth was pretty wide. For a receiver, it should operate just fine. The points where the antenna is the nost resonant may receive a bit better than way down at the band edges, but you'll hear just fine. For the price, its great. I've got a couple of bigger and better dual band antennas and they don't perform any better than the Tram.

I can't address all the techie issues about this antenna, but it work just fine with my scanner. I've had one for two years or so and I bring in signal from 75+ miles away in the two meter range and beyond, 136- 160+mhz. Uhf comes in fine. A local, with in 40 miles, uses Uhf 400, 460mkz range and it blows in, 5x5. So my answer to your question is , yes it does a great job, a great job seeing as how I live in a very rural area.

No, it doesnt work as a scanner just a cb-radio. It has two emergency channels but not for the purposes of listening to ems/police/fire.

The scanner will scan "low band" police frequencies by selecting the police service function key. Unfortunately, most law enforcement in the USA has switched to encrypted frequencies and they can not be picked up by this or any other commercially available scanner. You probably will not be able to listen to Police communications.

I only used it for scanner not xmit. It did no better than uniden supplied rubber duck which is very good. I have been unable to surpass it with anything. I have ken wood transceivers UHF and they do well on ken wood rubber ducks but UHF antennas on car roofs boost signal car to car.

I'm not sure. I would say no. I got mine to pick up 700mhz police radios. It works for that but otherwise I don't know anything about it

This scanner antennae would be almost useless for transmitting purposes on the cb band. Particularly forA base unit.

Yes. First thing is not get ahead of it. Its response to finding a signal is a little slow. It's a good, not great, product. Signal will drop out on occasion like others. Go with direct USB connection

I guess you would have to verify what frequesncy is available. This is Quadband and quite useful in most countries.

I bought a adapter at radio shack for $7.00 & use a CB antennae. it works better at pulling in weak or distant frequencies. if you take the indoor antennae that came with the scanner, radio shack can match it right up.

This unit can be used in a vehicle (if you are licensed to have one in the vehicle) or used in the home or office. It is not a digital scanner so it will probably not pick up most of the newer frequencies that most all the police, fire and ambulance agencies use now. I made this mistake but decised to keep the unit anyway. It comes with a telescopping antenna that plugs in the back of the unit.

Not at all friend. It has its limitations, including its frequency range and fidelity, It does the job very well though if you are looking for something decent...Regards.

We have tested this radio, line of sight, out to 7 miles. I'd say it would work well for this application. I would suggest a throat mike for bar security. The ear peice would be valuable

I use mine for a quad copter so you should be fine. Depending on the number of channels on your transmitter, you may be able to get by with fewer channels on the receiver for less $.

You could try it, but insuspect you will get a high swr reading. This means that when tou try to transmit the signal will be heavily reflected back into your radio. This will severely limit your broadcast range and eventually burn up your radio. Mounting away from metal is best.

You would most likely have a high SWR and a poor communication experience. An antenna matcher might help some, but only experimentation will tell!

I use mine for a police scanner that comes with a CD-ROM that formats the micro SD card and downloads available channels. You might have to get a micro SD card writer/reader in order to format the SD card.

Unless the scanner runs off a coaxial cable, I doubt it. This device is specifically for boosting signal in a long run of coaxial. It has some functionality in cleaning up signal noise, but again I doubt it does what you wish it do. There is other equipment specifically designed to clean up and boost signals transmitted and received by radio equipment. Ask a ham radio operator or equipment stores that service ham radio.
