What is the transmitting and receiving range? I need some thing for long distance

Line of sight as far as you can see. If you have a good antenna (to a certain extent, bigger is better) and a good location (up high above everything) you can easily get over 80 miles direct. I use a repeater (located on a mountain top) that is about 80 miles from me and it is no problem. My signal relayed through that repeater can go even farther, another 100 miles.

The device manual says that it can transmit up to 150 feet distance. It is always best to have the device near the wireless receiver, if possible. It should be able to send across several floors as long as the signal doesn't get obstructed. I believe your distance from the tower to the device will play a bigger role in signal strength than from the device to the wireless receiver. You can also connect an external antenna to the device if it cannot get a good signal from a tower.

Get the Extreme with the amplifier, it works great at those distances. You may need to place in a window towards the transmission tower in your area. Use the included power adapter, as it produces a bit more current and seems to work better. I have used the Extreme at those distances, and I am receiving 40 plus channels.

only if you use alternate software. look up sdrsharp. i have picked up transmissions from 28 mhz up to 800 mhz but this will work well outside that range i just don't have the antennas to pick up the lower frequiencies. hope this helps

I believe the range is 500 feet. I can walk out to the mailbox (country road) and to a back shed on our property of 2-1/2 acres. My phone or any other device is no problem.

I'm not sure of the exact range of this alert system. I had a distance of about 1/3 mile from transmitter to receiver. Regardless of the range, I would not recommend this product to anyone as it only worked for a few weeks before it started giving false alarms or didn't alert when someone was actually coming down the driveway. Look elsewhere for an alert system!

The transmitter, which is connected to your receiver via one or more cables, finds the speaker with a radio signal. Mine is about 20 feet from the antenna with one wall between them.

Hmmmmmmm, tough one . I've never had to use it for that distance. I connected to an AP that was about 300 Yards away, thru trees and homes.

My husband believes it's 50 or 60 feet. Let me preface that to say that we have to go through our house and garage with a lot of metal between both. That tends to disrupt other wireless products we've used and made them almost useless. This works fine, so I don't really know if this answer helps or not. There is no "line of sight" between the transmitter and receiver for us.

unless you make a duplex directional wi fi transmitter antenna and duplex receiver or have a few signal boosters along the way 2,640 feet is a little far for wi fi no matter how good the equipment. If you go line of sight no obstructions at all I have been at 400 feet. but i will not leave equipment out side to have that range.

I doubt if a different antenna will increase range as this is limited primarily by transmitter power and the sending unit antenna is fixed. Perhaps a larger antenna on the receiver might help but I found that distance is primarily limited by obstructions, so if you can mount the receiver outside in line of sight to the sender you can experience maximal range. This antenna has a screw on coaxal type connector approx 1/4 inch diameter - the receiver has the male fitting.

I'm not entirely, sure-I believe the main transmitting antenna I was picking up while it did work were about 10 miles away. It worked for a few months, then died. I bought the RCA antenna at Fry's with a pre-amplifier, works better and is still working.

It shouldn't be an issue, it has a pretty strong wireless signal. I would say it will reach at least about 6 feet from your receiver (The USB port).

It has a long range. I can get 200-250 ft from the phone before it disconnects

I don't think that is possible. The device transmits a wireless signal which almost by definition will be received by a wireless receiver tuned to receive in that frequency range.

Expect 20-30 feet, normal BT range, but depends on where the receiver is plugged in at on your PC and ambient conditions.

My range is at times as much as 50 feet. Most of the time I can have the transmitting source at one end of my home and I can venture to a different room at the opposire end before the Knivio begins to lose contact. There are instances when the range is much less. My range is reduced when the transmitting source is inside and I step outside the home. Reception is lost when the separation is as little as 10 feet. Another instance is when my bathroom's tiled walls seperate reception from transmission. Even at less than 7 feet.
