What is the practical max range for this unit?
1470955
Depends on the landscape, but in a suburban environment, with both stations at ground level--1 mile or less

In testing the unit in the field with a 15" laptop and Samsung Galaxy S4 cell phone, we have received a usable signal (stronger than -80dBi) line-of-site range of about 800 foot radius. We have deployed units indoors, usable signal through four drywall walls was about 200 foot radius.

Hi. I hesitate to answer this because I am not sure of the exact range of these devices. However, I can tell you that it is being used for communication purposes from the "main house" to what most people would consider an In-laws quarters way on the other side. For the price and the quality of the device, the worst thing that could happen is that you would have to send it back. Probably worth the try! Hope this helps.

The range really depends on if the outlets are on the grid. Even in the same house sometimes it may be "out of range"

Your word choice threw me off, so here is what I have: Two receiver units that can run on batteries or A/C plug, for hearing your child, AND one transmitter unit that stays wherever the child is and runs on A/C only. I am the grandpop who bought this and don't know the extreme range, but my daughter's house is a 50 foot long split level and they have no reception problems. Baby was born in December so outside use has not been done. We are all more than satisfied with the quality of this product. I hope this answers your questions sufficiently.

I have never tried to get an exact range but I do know other reviewers said it doesn't hold a steady range. It also failed very soon after the warranty period.

If you're planning on using the 'rubber duckie' antenna that comes with the unit then no you can't get that range. However, with an outside antenna with at least 3 decibel gain that 1 km range is possible. Mount the antenna as high as possible and away from obstructions. You should possibly check with the FCC (if you're transmitting in the U.S.) for their regulations concerning these FM transmitters.

I'm using one that is 12.5 inches long. I can hit a 440 repeater 20 miles away from inside my house. I can also hit a 2 meter repeater 15 miles away. Although the reports are not full quieting, when I go outside the signal reports improve dramatically.

I use mine as a back-up radio when I fly. The best ground range I have gotten from it is about 5-6mi. It is of course low-power, so line of sight is important to achieve best performance.

In general, I agree with Mike about the range (25-30 feet), but I found that walls in the house can interfere and shorten that range. I really like this device and have been using it for over a year now to watch videos while exercising. No problems at about 10 feet. I don't know the frequency but haven't noticed any interference issues with cordless phones or wifi.

There are too many factors for anyone to give you a good answer regarding a possible increased range. For example; Is there a device nearby that may be degrading wireless signals in general? Poor electrical connections, a fridge capacitor failing, etc all can create problems.

It has pretty good range. I have a large 1880-era brick house filled with plaster walls. I can get a signal 50 feet away outside on the porch or patio (with windows), and stream to a TV equally far away on another floor.

I am not sure of the exact range, we have a good sized yard, and never had a problem with range in the house or outside.

I don't think there is any functional limit on range in a home because the signal is wired. The range of a wifi that is used (from AV plug to wifi router like Airport Express) would be like any other wifi router that was used directly connected to the broadband modem.

Not sure about max range, I was using and getting hits in the 6-8 ft range. A lot of false positives though.

My device is in the middle of my house. I would say about 25 feet is the effective range
