Our take on the ProComm 17' RG58AU NMO Mount Antenna

This is a 17-foot RG58AU coaxial cable with an NMO antenna mount, made for running a mobile antenna to a radio in a car or truck. RG58AU is the stranded-copper version of standard RG58, so it tolerates the flexing and vibration of vehicle installs better than solid-core coax. The FME female connector at the cable end needs an FME-to-PL259 or FME-to-SMA adapter to mate with most radios. It suits CB, VHF/UHF and scanner users who want a ready-made NMO feed line rather than crimping their own.

Pros
  • Stranded RG58AU center conductor handles vibration better than solid RG58
  • 17 feet reaches from a roof or trunk mount to most dash locations
  • NMO mount is the standard base for interchangeable mobile whips
  • FME connector keeps the cable slim for routing through tight gaps
  • Works across CB, VHF and UHF bands with the right antenna
Cons
  • FME female end needs an adapter before it fits most radios
  • RG58 loses more signal than RG8X or LMR-240 on long runs or at UHF
  • No antenna included, only the mount and cable
  • Thin coax jacket is less durable than heavier mobile cable

What reviewers say

Owners of this type of NMO coax assembly generally report clean reception and a solid mount, with the FME connector being the main point of friction. Complaints center on needing an adapter and on RG58 limits at higher frequencies.

What people mention
  • ConnectorCriticisedBuyers say the FME female end needs an adapter, which catches people out.
  • Signal lossMixedFine for CB and short runs, but owners note RG58 loses more at UHF than thicker coax.
  • BuildPraisedThe mount and stranded coax hold up to vehicle vibration and routing.
  • LengthPraised17 feet covers most roof-to-dash runs in cars, SUVs and pickups.
  • SetupMixedRouting is easy, but the adapter step adds work before the radio connects.

Questions and answers

Does this plug straight into a CB radio?
No. The cable ends in an FME female connector, so you need an FME-to-PL259 adapter for a CB. Buy the adapter with the cable.
What antenna fits this mount?
Any antenna with an NMO base. That covers most CB, VHF and UHF mobile whips, so you can swap antennas without replacing the cable.
Is RG58AU better than regular RG58?
RG58AU uses a stranded center conductor, which handles flexing and vibration in a vehicle better than solid-core RG58. Signal loss is about the same.
Will it work for a UHF or scanner setup?
Yes, but keep the run short. RG58 loses more signal at UHF than RG8X or LMR-240, so long routes to a 70cm or scanner radio may underperform.
What is included?
The 17-foot RG58AU cable with the NMO mount and FME female connector. No antenna and no radio-side adapter are included.
Can I cut it to length?
You can, but you would need to fit a new connector and crimp it properly. Most buyers leave the full length coiled out of the way.
