Let me go completely OFF TOPIC here.

Why exactly do you need a whistle? The chances are, if you have an emergency in an urban area, then you can just call for help. The main reason why you might not want to do that - is because SOME of the people in your area are NOT friendly. In which case, a whistle isn't much help.

A cell phone is a much better signaling device. Because you can get a message directly to people who CAN come and look for you. But the main problem with phones is that signal reception can be poor. THEREFORE, what you really need is a portable antenna for a cell phone that BOOSTS the signal strength.

It seems to me that this choice might be a LOT more useful in an urban situation. I need to do the same thing myself - get some sort of portable antenna for my cell phone.

How is that portable antenna connected to the phone?

You can buy home and car cell phone boosters/repeaters. There are also printed antennas that are supposed to attach to the back of your phone, but they seem gimmicky.

EDIT: As previously noted, whistles are cheap insurance.

I think of a whistle as something I would use in an outdoor setting, but even so, a whistle requires much less energy to activate, especially compared to shouting. If you are buried in the debris generated by an earthquake or tornado, you will probably appreciate the difference.

Just getboth a whistle and an antenna booster.Both are pretty small.

I try to be at least somewhat equipped to survive without using electronics. A whistle is on the short list for that category of equipment. Anyway, I use a whistle regularly for biking, snowboarding, coaching, and generally getting a person's attention who is far away.

I wouldn't trust the little printed antenna that goes on the back of your cell phone. Get something with a big antenna and an amp requiring a power source.

I have something made by Wilson Electronics. I don't know how good this brand is, but it has made a difference in a communication situation. However, it wasn't as big of a difference as I'd hoped. I was driving on a highway and I needed to make an urgent call. I still had to drive a bit before the signal was strong enough.

Just occurred to me: you can probably find more informed opinions on cell phone forums.

As for whistles, the Nitcore is so tiny -- smaller than a key -- there is really no reason why you shouldn't have one on your keychain, along with a keychain light like Doug Ritter's Photon. Maybe a multitool, too.

YEAH I definitely need to buy a professional cell phone booster. I have had far too many problems with reception dropping out. It's worth having a good booster, because if you walk to the top of a hill, or a parking structure, you should be able to connect.

A whistle, in an urban setting, is a very effective signaling device. However, it is not specifically for summoning HELP, it is for summoning ATTENTION. This is why traffic cops and crossing guards routinely use them. I have effectively used a whistle in urban emergencies to stop traffic, help control crowds and to alert pedestrians to danger.

It's also good to cause one's free-range recombinant DNA to look around and perhaps be receptive to parental instruction.

Also, carrying both a cell phone and a whistle is not burdensome. However, not trying to brag, I can curl a 3-pound dumbbell for 5 reps easy...so yeah.
