Review: Great Antenna - Awesome antenna. Using a mag mount for inside use. Hits a lot of the repeaters in my area.
Review: Fantastic broad band antenna: Covers Amateur 2m/70cm, Marine VHF, MURS, GMRS - I bought this antenna primarily to use on my boat where I wanted to shared an antenna feed with both a GMRS radio, and a Marine VHF radio using a frequency-split diplexer. In that application it works great. Signal strength is very good, SWR at those frequencies is very good (<1.3:1) and installation was exactly how I expected. But then I discovered that this is also just a great all around antenna for 2m, 70cm, MURS, GMRS, Marine VHF, and in scanning (receive only) applications from 25MHz to 1.3GHz. I have one hooked up to my RTL-SDR, for example, so I can scan any service within its bandwidth range. The fold-down is rather stiff. I don't use this in offroad conditions currently, so I don't need a spring. But a spring kit is available if you need it to be better protected offroad. It's a rather long antenna due to its compatibility with 2m VHF. But it's a good all around antenna, very effective at the ranges I've tested. Recently I used it to hit a GMRS repeater 64 miles away with a 4w handheld.

## Features

- Wideband dual band performance enables operation across the full 2M and 70cm amateur bands with extended coverage for VHF and UHF public safety, commercial, and scanner use Designed for users who need more than standard ham band operation, the CA-2X4SRNMO covers a broad frequency range with optimized tuning to support amateur radio, commercial frequencies, and general scanning applications.
- High-gain mobile antenna design provides strong transmit and receive performance for communication in urban, rural, and obstructed areas Its efficient radiating structure enhances both outbound and inbound signal strength, making it ideal for mobile operators who require reliable communication over varying terrain or long-distance repeater paths.
- NMO connector base ensures compatibility with the most widely used mobile mounting systems, allowing easy integration with magnet mounts, trunk mounts, fender mounts, and permanent NMO installations The universal NMO standard provides a secure, weather-resistant connection and makes upgrading from other NMO antennas simple without needing to replace the mount.
- Flexible and durable whip construction resists wind, vehicle movement, low-clearance conditions, and vibration during travel The CA-2X4SRNMO’s flexibility greatly reduces the risk of bending or damage during everyday driving, offering long-term reliability for commercial fleets, emergency responders, and amateur radio users.

### ⭐⭐⭐⭐⭐ Great wideband mobile antenna
*by A***7 on January 5, 2026*

This is a really good mobile antenna suitable for HAM as well as GMRS/FRS communications. It has a pretty widebanded operation and has held up well over the years. I own 5 of these antennas and they are my favorite, go to mobile antenna. I have only every used this antenna with a mag mount and it works just fine. Good purchase!
