If you frequent theme parks such as Disney, Sea World or Dollywood you know cell phone usage can be a challenge.

I suggest using two-way radios to conserve battery power for your phones which also serve as your camera right?

If you and your part are licensed Amateur Radio operators stop here and use your hand-held (a.k.a. "HT"). If you would like to become licensed as a Technician Class which is perfect for this use-case visit http://www.arrl.org/getting-licensed. Advantage here is power and clear frequencies. You can often use 5 watts or more legally and well made radios that support that.

If you are not interested in getting a Ham Radio license here are your remaining options:

You will need about 5 watts honestly if the park if your normal sized theme park. Add to terrain Dollywood in particular is on the side of a mountain range and very hilly. You may need even more power to reach say the parking lot to the opposite end of the property. UHF cuts through mountains and hills better than VHF frequency range. If you look at Dollywood's radio system it is all UHF. See https://www.radioreference.com/apps/db/?aid=1755.

There are four classes of two-way radios available for your average consumer outside of Amateur Radio (See FCC Rules & Regulations Part 95: CB, FRS, GMRS and MURS

  1. CB radio is allowed 4 watts and although they make CB hand-helds they are all AM modulation (although that is about to change) and in the 27 MHz frequency range and typically bulky in size thus in most cases CB radio is ineffective at a theme park.
  2. FRS does not require a license but is limited to 500mA (as of 2017 the FCC allow up to 2W of power on all current FRS channels, including those shared with GMRS however 2W radios are slow to emerge on the market). But still 2 watts in most cases is probably not enough power particularly for Dollywood unless you are all inc lose proximity all the time. FRS is all VHF frequency range.
  3. MURS also unlicensed, with 2W power limit. There are very few MURS certified radios on the market and it's VHF.
  4. GMRS is UHF. You need to get a license from FCC for the modest fee and then you can transmit up to 50 watts on simplex and repeater GMRS channels. You also need GMRS type-approved radio to use these channels legally.

Note from the FCC Rules Part 95-1791: "Effective September 30, 2019, no person shall be permitted to manufacture or import, sell or offer for sale any radio equipment capable of operating under both this subpart (GMRS) and subpart B (FRS) of this chapter."

Also note there is the Land Mobile Service which also licensed under

So it seems GMRS is the obvious way to go. Here where the problem begins.

There are very few high power (>4W) handheld GMRS approved handheld radios on the market (and none that support repeater frequencies). There were a few high quality commercial Part 90 radios that were also certified for 95a (GMRS) but those are discontinued long time ago.

The product in question is one of the few ones that produces honest 5 watts - confirmed on FCC web site by looking up FCC ID and relevant lab measurement reports.

So what to get?

Well I strongly advise going the Amateur Radio route as a Technician Class license even if this all you use it for you are prepared or at least capable for an emergency. Not thast efveryone in your party (or those who will use the radio) must be licensed. Besides you might like it and become more involved in the hobby. https://www.youtube.com/watch?v=ee_SkP-INsQ
