9 dBi Low Profile N-Male Omni Outdoor 915 MHz Antenna for Helium SenseCAP M1 Bobcat FreedomFi MNTD

$18.00 $69.97

This is the newest to our low profile lineup of Helium/IoT antennas. Using the same size fiberglass casing as our 32" 5.8 dBi antenna, we were able to use a different internal copper length and coil to achieve 9 dBi. This allows for a lower profile height vs. conventional 9 dBi gain antennas that may exceed 40 inches. A lower profile design works similar to a full size but is cheaper to manufacture, transport, and ship to you, which means a lower price point.

Our 9 dBi 32" low profile fiberglass antenna with an N-Male connector and U-bolt bracket mount is certified and designed for outdoor environments and is weatherproof. 

This antenna is compatible with MNTD Hotspots, RAK V2, Bobcat 300, Nebra Indoor, SenseCAP M1, Kerlink, Linxdot,, Helium Hotspot, Kerlink, FreedomFi & LongAP, but requires an RP-SMA male to N-female coaxial cable to fit, and we carry compatible coaxial cables. It also works with other Helium hotspots (such as Nebra Outdoor) but may need different cable connectors, please contact our sales staff if needed.

1.1 - 1.2 SWR @ 915mhz on analyzer

Haven't had a chance to test actual range compared to other antennas yet but on a nano vna analyzer they tested out between 1.1 - 1.2 SWR @ 915mhz. That's about as perfect as you would get for an SWR.

Will be curious to see how these perform against a 5dbi Amazon foldable antenna in an apples to apples wisblock meshtastic test. Will update once that's done.

So far based on SWR and the build I'm impressed.

9 dBi Low Profile N-Male Omni Outdoor 915 MHz Antenna for Helium SenseCAP M1 Bobcat FreedomFi MNTD

So far so good. The antenna is working

Kellen Schauermann
Great antenna!

Hot installation up and it’s working well so far.

Ryan Brown
Good antenna

Everyone's situation is unique, height and location being the main factors. With that being said, my witnesses have become much more consistent. With as bad as the whole Helium network is now, I think it's about as good as I can get. Price is awesome too

New 9 dbi outdoor antenna

I made the foolish mistake of buying a "10 dbi" antenna from Amazon. My transmit scale was NA, within 24 hours of installing the Rokland antenna I had my first rewards and 1.00 transmit scale in a sparse woodsy/mountainous area. Don't waste your time with those no name antennas. Just pay the extra $20 and get a Rokland
