Specification Brand : SIGNALPLUS BulletPoint1 : meshtastic antenna Frequency :915MHz;Gain : 10dBi ;length:90cm ; Antenna Connector:N female ;Higher gain, Longer range. The more the influence of signal loss can be avoided. BulletPoint2 : Applicable to all meshtastic devices/ miner brands :AU915 linxdot hotspot ,Rak Miner 2v, kerlink wirnet ifemtocell miner, cotx-X3 heluim miner ,LinxDot ,FreedomFI ,bobcat 300 ,finestra miner ,sensecap,syncrobit, etc . BulletPoint3 : Material :(antirust) the helium miner antennas is made of fiberglass. The antenna structure inside is made of copper.The copper (element) tube is better than the circuit board. The copper (element) tube enables the antenna to obtain lower VSWR and withstand higher power. BulletPoint4 : Use skills:Any antenna is heavily dependent on the surroundings.To achieve better results you may have to move around your hotspot and antenna(height and location of the installation)until you determine a sweet spot that gives you the best rewards.You must take into considerations, antenna hight, location,building clearance, line of sight, Issues with the blockchain wide system ,type of hotspot used etc. BulletPoint5 : Updating antenna in helium app :You can use "custom" or choose any brand. BulletPoint6 : Connector :the cable with N-Male on the end (for this antenna). The type of connector at the other end of the wire is RP-SMA female (for miner ).and the package is include a RP-SMA male to SMA male adapter ,you can use it if your device is SMA connector . BulletPoint7 : Packing Listing : 1 x 915mhz lora antennas 915mhz & 1 X 10 meter of SMA RG58 Cable & 1X SMA Female to RP-SMA Male Adapter & 1set U-clip code BulletPoint8 : This item can be returned in its original condition for replacement within 30 days of receipt. 100% satisfaction guarantee. If you have any questions about the product, please feel free to contact us BulletPoint9 : Inside /Outside /omnidirectional/Waterproof/Snow : You could put it inside if you need but outside would be even better.the cable and antenna is designed to be waterproof and will last all seasons outdoors.Dimensions of the mount :The mount fits poles whose diameter between 35mm and 50 mm.
