Industrial Commercial Grade 8dBI Certified 900 915 927Mhz Helium Ham DMR Antenna

Description: Commercial Grade Super heavy-duty Antenna for 900-930 Mhz great for Helium miners. Great for 902 927 Ham DMR 100 Watt repeaters. Its a certified 8 dBi gain (in our antenna test chamber). It is 47" tall with a 1.5" thick-wall radome tube plus a 1.75" OD base bracket sleeve of heavy extruded aluminum. Includes the stamped aluminum saddles and straps plus 4 5/16" bolts and hardware. The connector is an N-type female which is the norm for all outdoor telecom antennas in this frequency range. UPDATE March 2023. Added some SWR screen pictures. The antenna is always "in-spec" at under 1.9:1 SWR. Production variables have the 1.1:1 SWR at either 915 center or 928 High. I can choose and segregate for the SWR obsessed Hams for either version if you write a note on the order. However, a 1.5 or 1.65:1 SWR is still great. I know the ham repeater high power Tx at 927 likes a 1.1:1 better. This antenna attaches to any vertical or horizontal tube/support being 1" to 2.75" diameter. This antenna's mechanical parts were originally made for export to government users on special frequencies. Now we can use the parts for 915 Mhz antenna systems. This antenna provides 8 dBi gain 360 degrees around with an 24 degree elevation. (Plus and minus 12 degrees from horizon). It is designed and made in USA using US and import parts. Watch other listings for our single and dual panels, plus our new Chinese 8 dBi also certified in our lab and much cheaper. Every antenna we ship, made in USA or Asia is RF tested before shipping to make sure there are no duds, ever. attn Miners! This antenna is tested on an RF analyzer and vibrated to make 100% sure its working perfectly. If you dont see your expected "witness" count or miner results, its NOT the antenna! Check your cable, connectors, and location. If you have to return it do not call it defective, please. Notice about the heavy marine grade finish. There are some paint chips from rough handling in the warehouse of the bulk raw tubes. This has no performance or weathering issues. The tube under the paint is epoxy fiberglass composite and smooth not porous. If the chipping is a problem, do NOT buy this antenna.
