Best Cables for Connecting High Gain Antennas to Helium Miners

Posted by Michael Crudele on

We get this question daily: What cable do you recommend for connecting a high gain external antenna (with N-Female connector) like the ROSA-902-5-SNF or ROSA-902-8-SNF to my 900 MHz Helium Miner?

There are two options for this:

Option 1: You can connect the antenna directly to the Miner (that works fine if installing indoors, in covered area (like a balcony), or if the chance of lightning striking your antenna is minimal.

Option 2: You want to utilize a lightning arrestor between your antenna and your Miner if you have any concerns about lightning striking your antenna (a strike will definitely destroy your Miner)

For Option # 1

Simply go to our webpage and configure the cable as follows: https://www.arcantenna.com/collections/cable-builder 

Choose cable type PT240 for lengths up to 55 feet, choose cable type PT400 for lengths over 55 feet. Next choose the appropriate cable length for your installation. Connector # 1 should be type RSM (RP-SMA Male) which connects to the Miner and Connector # 2 should be SNM (Standard N Male) connects to the antenna. Please be mindful of the fact that cables are NCNR non-cancellable & non-returnable, so double check your choices.

 

For Option 2

If you want to add the lightning arrestor, then start by purchasing a UL rated lightning arrestor like the RFMAX # RSP-90-3-SNF-SNFBH.

Keep in mind you need to crimp a copper grounding wire (sold separately at Amazon or Home Depot) and bring that to an earth ground. You can find ideas for getting that done by searching Google “how to install to earth ground”  You will need TWO cables for this set up. One to go from the Miner to the lightning arrestor, and one to go from the lightning arrestor to the antenna. 

Go to the cable configuration tool at: https://www.arcantenna.com/collections/cable-builder 

You’ll want a short cable to go from the Miner to the lightning arrestor (like 5-15 feet)  Choose cable type PT240, and the appropriate cable length for your installation.  Connector # 1 should be type RSM (RP-SMA Male) which connects to the Miner and Connector # 2 should be SNM (Standard N Male) connects to the lightning arrestor.  The second cable will go from the lightning arrestor to the antenna.  Choose cable type PT240 for lengths up to 55 feet, choose cable type PT400 for lengths over 55 feet, then choose the cable length appropriate for your installation.  Connector # 1 should be type SNM (Standard N Male) which connects to the lightning arrestor and Connector # 2 should also be SNM (Standard N Male) which will connect to the antenna.

 

Again, please be mindful of the fact that cables are NCNR non-cancellable & non-returnable, so double check your choices.
