PURPOSE
These kits are designed to choke common mode currents going into or exiting from your Tuner Genius cables. Filters are supplied for the RF Input (s) RF Outputs, DC power and LAN input. The DC power line choke helps keep common mode current out of the power line which could cause interference to other devices connected to the same power line if not suppressed. The LAN cable choke keeps any RFI off the LAN cable input.
USE
RFI-AT-FLEX-TG Standard kit for tuners with SO2R option and RFI-AT-FLEX-TG3 for tuners with 3 antenna outputs option (1X3).
Note if you use other cables into the tuner such as PTT or otherwise, use FSB31-1/2 snap on ferrites for these lines and wind 2 or more turns thru center if possible. These ferrites sold separately.

INSTALLATION GUIDELINES
SO2R Kit - Part# RFI-AT-FLEX-TG (2 Inputs, 2 Outputs)
RF Output:Snap On Filter (1” ID) – 3 turns (1/2" cable) or 6 turns (1/4" cable) of coax cable through center for each output - Use 1 for channel A and one for channel B Output
RF Input Snap On (1" ID) - 3 turns (1/2" cable) or 6 turns (1/4" cable) of coax cable through center for each input - Use one for channel A and one for channel B Input
Ethernet Cable:Snap On Filter (1/2” ID) – multiple turns through center
DC Power:Snap On Filter (1/2” ID) – 2 or more turns of DC (+ and -) power cord through center
3 Antenna Kit - Part# RFI-AT-FLEX-TG3 (3 Antennas, 1 input)
RF Output:Snap On Filter (1” ID) – 3 turns (1/2" cable) or 6 turns (1/4" cable) of coax cable through center for each output
RF Input Snap On (1" ID) - 3 turns (1/2" cable) or 6 turns (1/4" cable) of coax cable through center for TX input
Ethernet Cable:Snap On Filter (1/2” ID) – multiple turns through center
DC Power:Snap On Filter (1/2” ID) – 2 or more turns of DC (+ and -) power cord through center
Also make sure you connect a good RF ground to the tuner ground post.
We specify impedance ratios as an output to input ratio where the output (or load) is given first and the input is given second (e.g. 100:50 (2:1) would mean a 100 ohm output and a 50 ohm input; a 25:50 (1:2) would mean a 25 ohm load and a 50 ohm input). Most all products use a 50 ohm input unless otherwise specified.
We have products that are available as kits for the do-it-yourself (DIY) person or fully assembled and tested units for the “Plug & Play” crowd.
Our impedance transformers are available using two different topologies: Binocular cores or toroid cores with multiple turns for increased effectiveness and wide band frequency transformations. We utilize single and multiple core transformers using high order windings when needed to extend product performance.
We rate the power ratings as watts PEP (Peak Envelop Power) with standard duty cycles for various modes. To determine the PEP rating required for your needs, see: Choke & Transformer Power Ratings
