Quick note:
For cell service several things are important to know.
For cell service several things are important to know.
- Every carrier uses a different frequency, type of transmission, encoding etc. so what works for AT&T probably won't work as well if at all for Verizon.
- 3G and 4G use different Frequencies
- 1/2G for the most part has been depreciated or will be soon. AT&T used to support a lot of cellular alarm systems and game cameras in this range but they won't work now in most places (but you can buy them on eBay cheap)
- Each manufacturer of cell phones has different jacks/adapters/hook-ups for their equipment to use external antennas. Some have taken the option out of the system an you have use a wireless device to link to a real antenna.
- Antennas can be focused on one carrier and signal band or can but a multi-band to cover everything. Guess which type is cheaper

- A multi-band antenna is a compromise, you are trading off a 100% solution for one specific use for an 80% solution for flexibility to multi-task. This isn't necessarily a bad thing.
- There are cell system set-ups for Car, Marine and fixed location.
