This listing includes the divider described below, 2 cables (lab grade) and N/SMA adapter. Connect 2 Helium directional panels our model COM-9028P 3.5" apart to increase the single's 8.9 dBi to be 12.1 dBi. This kit is for 2 directional antennas which have to be the same model or type and spaced apart correctly. I know the spacing of our panel antennas but I would not know the spacing of other antennas

Inventory closeout of our 820-950Mhz low-loss power dividers. These were made here in the late 90s for the 1G US and Euro cell phones. 

These are GREAT for LoRa Helium radios because they are compact, and most especially because of the ultra-low-loss narrow band design. The insertion loss is an amazing low 0.1 dB due to the narrow band design, precision CNC machined housing and small size. For comparison, see all the wide-band dividers on the market with N-female connectors. Those wide-band splitter-dividers will have 0.3 dB loss for the best ones however most low-cost ones are over 0.5dB loss per port.

The SWR for these devices is under 1.2:1 at the 850-950 band which has Lo-Ra right in the middle at 902-928.

Remember, each port will be -3dB or in this case 3.1 dB less than the main input, The 3 dB is half the power, The -3dB is called division loss, the 0.1 dB is called insertion loss.

Notice some measurement pictures in my antenna lab, I also measured a 4-way model that day and posted a separate listing. The measurements are always made with a 50 Ohm load at the open ports. Those dummy loads can be seen in the pictures and are not included. Make sure to have 2 antennas or any 50Ohm antenna or dummy load on any open port plus of course the radio on the other side single port.

These are all standard SMA female connectors on the device, NOT the SMA RP versions used for WiFi and Miners, etc. Cable and adapters are included in this ebay listing.

These devices can also be used to put 2 radios on 1 single antenna! Port to port isolation was tested at 20-25 dB which normally protects a radio on the other port. However data radios on the very same band will not work well. Not for 2 miners on 1 antenna!

These are unique high-quality items once sold out will never be made again.  Size is 2.5 x 2.0 x 0.5" made of CNC machined aluminum, circuit printed on Rogers low-loss PCB. Wilkinson circuit.
