Product Details

The Digital Antenna C118-20 is a professional-grade 20-foot extension cable designed specifically for Digital Antenna's 500 Series VHF and AIS antennas. This marine-rated cable provides an easy solution for extending your antenna connection when additional length is needed for installation flexibility.

Key Features:

  • 20 feet of premium RG-8X marine-grade coaxial cable with low loss performance
  • Tinned braid construction with foil shielding for superior corrosion resistance and signal integrity
  • UV-stable jacket designed to withstand harsh marine environments
  • Factory-installed mini-UHF female connectors on both ends for reliable connections
  • Includes DA624 mini-UHF double male adapter for seamless connection to 500 Series antennas
  • Compatible with all Digital Antenna 500 Series VHF and AIS antennas

Installation:

Connect the included double mini-UHF male adapter between your 500 Series antenna's mini-UHF female connector and the extension cable's mini-UHF female connector. The cable's opposite end accepts the 500 Series antenna's standard PL-259 adapter, providing a complete connection solution.

This extension cable maintains signal quality while providing the additional length needed for complex installations, tower-mounted antennas, or when routing cables through bulkheads and cabin spaces.

Cheap prices good service.

Fast and easy.

I'll start off saying that Autoplicity's prices are unbeatable...but, I placed my order on a Saturday night (which I know is the weekend)on a in stock part and it took them till the following Thursday to ship it out. I use my truck to make a living and was hoping to get it a little quicker, but now I'm down another 3-4 days till the part gets here. Also, I sent a e-mail on Tuesday evening regaurding my order and never got a response.
