Helium Miners: RFMAX Antenna vs Rokland/HNtenna

Posted by Michael Crudele on

One of the most important factors in choosing your Helium Miner Antenna is the gain. The gain of an antenna is directly affected by the height. The RFMAX ROSA-902-8-SNF is 65 inches long, and thus is able to produce a TRUE omni-directional gain of 8 dBi which provides greater coverage laterally. Additionally, this antenna is high quality, durable, outdoor tested and features a drain hole so you can use it outdoors with no worries. You can see the omni-directional field pattern shown in the charts below:   The issue with using other antennas, such as Rokland or HNtenna, for a Helium Network...

What is the Best Antenna for GMRS Radios for Off-roading?

Posted by Michael Crudele on

What is the best antenna for off-road vehicles (jeeps, UTV’s, dune buggies) using GMRS, or General Mobile Radio Service? The GMRS frequency ranges between 462-467 MHz and is excellent for off-roaders looking to stay in touch out on the trails. These antennas ideally utilize a metallic “ground-plane” of at least 1x1 feet (like the roof of a truck) but in the off-road world that usually is not possible. Most GMRS antennas get mounted on fenders, bumpers or spare tire hitches.
