2 channel BNC cables for RF
« on: February 11, 2015, 04:02:12 pm »

I am not sure if this is a no-no type cabling situation... but Is there a manufacture making a 2 channel BNC, 50 Ohm cable for Wireless Antennas?  Or a Multi Channel BNC/50 Ohm cable?


Heres what I am thinking:  I am wanting to build the RF rack based on the 6 pc CORE band (2 Wireless Mics & 3 Transmitters for 6 mono IEM mixes) and then I want to build a small supplemental rack for when we have horns at the event and that rack will consist of 2 Wireless Horn Mics and 1 IEM Transmitter (2 more mixes).  Its not a problem to throw the 4th Transmitter into the band rack, but I'd rather save a space/weight for the other 2 mic rack units and run a small BNC snake to plug into the Antenna Distros.

I've seen exactly what you're looking for, but only in 75 ohm cable. We have some at work, it's essentially 2 RG6 in a dumbell configuration, and it's typically used with satellite dish systems. It's cheap and it's a pain to coil, but it's intended for install use so I guess that doesn't matter so much. We also have nice 5 and 10 channel Belden RG6. That stuff is in a round overall jacket, which makes it easy to coil, but it's heavy and the diameter is very large, especially on the 10 channel.

The 2 channel 75 ohm RG6 would likely work fine for your project, despite not being the "right" cable for the job. The problem is that all the 2 channel stuff I've seen tends to be really cheap (it's intended for residential satellite dishes, after all), and not something that I'd use in a professional situation. I do occasionally use RG6 in places I "shouldn't", like for wireless antennas, but it's quality RG6. And it works fine.

That said, I've never seen, nor do I know of any 50 ohm multi cable. Not 2 channel, 5, 10, or otherwise.

I think your best bet would be to either heat shrink a couple cables together, or use braided sleeving and make a nice loom. Myself, I'd probably go for the braided sleeving. It looks nice and it's easier to change cables out if you need to.
