GMRS – Better For Local Communications
If you want a radio for talking to other vehicles or handhelds in the outdoors, and want the best range and most features, GMRS is the best choice, by far. While VHF radio waves – including CB – typically travel farther in rural settings, GMRS’s power advantage overcomes UHF’s slight range disadvantages to give longer range in most scenarios. GMRS may work better in wooded areas, since UHF radio waves can easily travel through small spaces. Retevis RA87 has 40w transmitter power, the communication distance is far enough. And RA87 is GMRS radio, you can apply for it if you are over 18 years old. After getting the license, the whole family can use it.
GMRS Uses Shorter Antennas
The size of an optimal mobile CB antennas is around 108″, while you can get GMRS antennas with similar gain as short as 35″. GMRS antennas short as 20″ can still “talk” for many miles in open country, something a short CB antenna can’t do. By “stacking two 5/8 wave antennas, GMRS aerials can more than double a 50 watt GMRS radio’s ERP, or effective radiated power.
Mobile Radio Antenna Mounts
There are several common variations when it comes to mounting a Mobile Radio antenna your vehicle. Choosing the best Mobile Radio antenna will depend on your vehicle and transmission needs.
- Magnetic mount: As its name implies, these utilize a magnetic base for mounting. They come with a coax, mount, and whip antenna. Transmission and receiving range vary by where the mount is placed on a vehicle, with antennas ranging between 3.0 and 5.0 in. for 3.0 to 7.0 miles of range. they perform well and are incredibly easy to install.
- Center-load: These are commonly called “trucker antennas” because of their frequent use on semi-trucks. They have a thick stainless steel lower shaft with a plastic-cased coil and whip antenna on top. These antennas are generally 4.0 to 5.0 in. long with a range anywhere from 7.0 to 10.0 miles. Although they perform better than most fiberglass and magnet mounts, center-loaded antennas are more expensive and prone to damage.
- Top-loaded antennas: This mount format is good for mobility and usually fairly affordable. Although commonly made of fiberglass and have great functionality for receiving and transmission, top-loaded antennas typically have lower wattage ratings due to using a thinner coil wire.
This kit has chosen a strong magnetic base stainless steel antenna. Stainless steel has a higher tensile strength, so thinner wire can be used. This makes steel an excellent choice for mobile whip antennas where flexibility is a must. No more worrying about permanent mounting or drilling into your RV. High stiffness due to short antennae. Stainless Steel Antenna is no susceptible to low bridges, parking decks, and tree branches.
The Magnetic Suction Cup Antenna is the perfect solution your mobile radio. This Suction Cup Mount will mount to any smooth, non-porous surface, of your RV will work perfectly. Just attach the suction cup mount to your RV near the entry point where the cable will come into your RV. That is all there is to it! This makes for a very easy and clean install. Before you leave for your next destination, just take it down.
