R174

[PM08203]

Looking for a recommendation for a vendor to supply R174 in 50 ft lengths with BNC male on one end and female BNC on the other.

TY!

Also look for LMR100 which is the same size but slightly less loss.

I've never seen an adaptor to put a PL-259 on RG-174 cable. Most RG-174 that I've seen has been for shielded connections on a circuit board, not in a feed line. Except for very short runs RG-174 makes for terrible feed line.

RG174 are almost 4 times worse than RG58 below 10MHz but gets better the higher the frequency. Twice as bad as RG58 at 400MHz and only some 20% at 900Mhz. So try to use only as interconnection with short lenghts between devices.

RG-174 adapters for standard PL-259s are quite common, here is what they look like.

By definition and specs, RG-174 has a copper braid that solders easily. Same with its Teflon counterpart RG-316 but the copper braid and center conductor is silver plated. LMR100 is the same size as RG-174 and has a foil/braid shield but you can still solder to it.

The adapters shown below fit all types I just mentioned.

RG-174 looks to be about twice as lossy as RG-58 at all frequencies from below 1MHz past 1GHz. An example of twice as lossy is double the loss as in RG-58 has about 1.17dB loss at 10MHz for 100ft and RG-174 has about 2.5dB loss. At 1GHz RG-58 has about 16.4dB loss and RG-174 has about 33.6dB. I'm not seeing any major difference in loss at lower frequencies with RG-174 over RG-58.

I've never seen the reducers or even seen them advertised.
