You need to use 75 Ohm cable with iDirect. The interface is at L-band and the IFL cable needs to carry DC voltage for the BUC and LNB and also potentially 10 MHz so the DC resistance is very important. iDirect recommend RG6 and RG11 in their installation documentation. I believe that TAC can give you a table of maximum cable run distances depending on the BUC you use.

Dear

Maximum IFL Lengths (Ku-Band):

RG-6

1Watt NJRC : 302.9 Feet (Limited by RF)
2 Watt NJRC: 302.9 Feet (Limited by RF)
4 Watt NJRC: 251.4 Feet (Limited by DC)

RG-11

1 Watt NJRC: 514.1 Feet (Limited by RF)
2 Watt NJRC: 514.1 Feet (Limited by RF)
4 Watt NJRC: 514.1 Feet (Limited by DC)

IFL Coax Cable recommended by iDirect:
1. RG11 Commscope , manufactured part number 5902, iDirect partnumber 4114-0002-0001, loss (dB/100ft at 1700 MHz) = 6.1, DC resistance (ohms/100 ft)=0.426.

2. RG11 Belden , manufactured part number 8213, , loss (dB/100ft at 1700 MHz) = 7.1, DC resistance (ohms/100 ft)=0.315.

Commscope 5902 lenght max are:

1 Watt NJRC: 514.1 Feet (Limited by RF)
2 Watt NJRC: 514.1 Feet (Limited by RF)
4 Watt NJRC: 514.1 Feet (Limited by DC)

like jawadg said.

Best regard,

Adrian
