    Interesting analogy. I don't have a tower, so I certainly don't fall into that category. :)

    I think the difference is that "goTenna" is trying to get you to buy the product with reasoning that appeals more towards the potential buyer's fears rather than being based on facts. The Ham with the tower is just trying to justify (perhaps only in his/her own mind) the need for the tower...not trying to sell you a product that you won't really need for the reasons advertised.

    I maybe missing something here (early morning after late night) but doesn't the name remind you of those annoying commercials about lady (and now men) product that allow you to sneeze, etc. without embarrassment as you get older?

    Only works between the ANTENNA UNITS so if you do not have one or are given the password to attach it does you no good. Its basically a tiny private network. So really, its useless for GENERAL use but great for people that are out in a place with no service in a group and want to keep in touch with each other.

    The difference between HAMS and this device is that ANYONE can send and receive using amateur radio as the signal is open for all to receive. Not so in this device. No device attached to your phone, you are STILL without service.

    It seems to be a little less than that. Their FAQ says it is most definitely NOT a mesh network, but only a direct point-to-point communications system. No store-and-forward, but it will auto-retry. The sender and receiver have to be within direct simplex range for the message to go through.

    It's basically a "digital walkie talkie for your cell phone", that pairs with a smart phone and allows you to send texts and share your location, but no voice communications. It does support end-to-end encryption, unlike ham radio. It's VHF, 2 watts, but a small package which must not have a very efficient antenna. I'm not sure what to expect as far as range, but I'd expect a pair of 2m HTs using simplex to do at least as well, being of a roughly similar wavelength, roughly similar power, probably better antennas (bad as HT antennas are!). They claim that, in city streets, range should be around 0.5 to 1 mile. That seems achievable. They also quote higher ranges under ideal conditions. As hams, we all know how variable range can be in low power VHF, depending on terrain, obstacles, etc.

    Did anybody put up a tower to achieve a 0.5 to 1 mile range? I've got a few things I'd like to sell to that fellow...

    Seriously, these things are not a lot different from FRS radios, as far as their ability to keep two people in touch over a distance without infrastructure. However, some people prefer communication by texts using smartphones instead of by voice, and these do that. Furthermore, by supporting encrypted digital communications that are addressed to a specific individual, you don't overhear everyone else's messages, nor do others hear yours, which can be an advantage over FM voice.

    I'll definitely pass on this one, but I bet they'll sell a few. I'm not sure what the market is for people who want to be able to text short distances, while out of cell service range. I wouldn't bet on this taking the world by storm, but then again, I didn't think anyone would want a camera in their phone.
