FAQ – Frequently asked questions

Is RG174 suitable for long cable runs?
RG174 is primarily selected for its small size and flexibility. For longer runs or lower attenuation, a larger-diameter cable is recommended.

What is the outer diameter?
The outer jacket diameter is 2.80 mm.

Is it available from stock and sold by the meter?
The cable is sold by the meter and availability is shown on the product page. For larger quantities, a dedicated quotation can be requested.
