Well let me confuse you some more lol
the FRS and GMRS radio's are UHF - MURS is VHF (not my words below in quotes)
"The quick answer is: choose VHF if you plan to only use the radios outdoors and in an area that is relatively free of obstructions, such as buildings. If you plan on using the radio indoors, both indoors and out, or outdoors but around buildings, choose UHF.
UHF signals don't travel quite as far outdoors as VHF signals, but they do a better job of penetrating wood, steel, and concrete, giving you better range and performance in urban environments and around buildings. VHF signals travel farther, absent obstructions, and tend to "hug" the earth better, providing better performance outdoors or in hilly terrain."
Here is how I see it. For riding in a group of people that is not spread out more than a mile a Handheld or HT will work fine. Most HT's allow you to set a code so that you only hear those transmissions that have the code embedded. if you don't have the code and are on the same frequency/channel you will hear them they just wont hear you.
Advantages of the HT are
- Portable (can take down hill to scout and radio back)
- Use of speaker mic - don't discount the ability to pull the speaker mic up to your ear to hear better in loud environments (just don't buy the Baofeng speaker mic - no one will understand you)
Advantages of Mobile:
- Never have to charge or worry about internal battery
- Audio can be turned up louder or use of external speaker
- Multiple power levels (remember legal limit on FRS is max of 2W, Legal limit on MURS is also 2W)
A lot of the issues I observed with the handhelds can be traced to 2 factors
1. Use of crappy speaker mics that distort transmitted audio so bad that no one can understand. This lead to believe that it was a power level issue or that a louder system would solve for.
2. Poor Radio Etiquette - Many times someone (including myself) will transmit out something like "Hey watch out for xx" - the issue is that the transmission was not addressed to any one and not announced. It is always better to call out to the person you want to transmit to and wait for their response before proceeding.
Also nothing worse than a chatter box on the radio - someone who just talks and talks hogging up a group freq where it can not be used.
Bottom line I don't think you need a mobile for takeover - if you want to stay informed and talk to your trail group- an HT should work fine - most HT's will also allow you to connect to external antennas as well.
