## Overview

The Diamond X50A is a rugged, factory-tuned dual-band base antenna delivering medium-to-high gain on both 2 meter (144–148 MHz) and 70 centimeter (435–450 MHz) amateur radio bands. Its durable fiberglass radome and stainless steel hardware ensure reliable outdoor performance, withstanding winds up to 135 MPH. Designed for easy installation with a standard UHF female connector and stable VSWR below 1.5:1, it’s ideal for amateur radio enthusiasts and repeater systems seeking enhanced coverage and clear communications.

## Description

The Diamond X50A Dual-Band Base/Repeater Antenna is a high-performance vertical antenna optimized for VHF and UHF operations in amateur radio, public service networks, and fixed station applications. Purpose-built for the 144–148 MHz (2 meter) and 435–450 MHz (70 centimeter) frequency ranges, this antenna delivers strong transmit and receive performance across both bands without the need for field tuning, thanks to its precision factory adjustment. At approximately 4.5 dB gain on the 2 meter band and 7.2 dB gain on the 70 centimeter band, the X50A provides medium-to-high gain characteristics that enhance coverage and repeater access beyond typical base station antennas. Its durable design includes a rugged fiberglass radome and stainless-steel hardware, ensuring long-lasting performance in harsh outdoor conditions while resisting corrosion and environmental wear. Rated for up to 200 W of RF power and engineered to withstand wind speeds of up to 135 MPH (without ice), this antenna is suitable for permanent installation on masts, towers, and rooftop mounts. The DC-grounded structure provides added protection against high-voltage surges, improving station safety and equipment longevity. Measuring about 5.6 feet (1.7 m) tall, the X50A offers a compact footprint without compromising performance, allowing it to fit easily on a variety of mast diameters while maintaining efficient radiation patterns. With a standard UHF female connector, it interfaces seamlessly with your existing coax feed line and support hardware. This versatile dual-band antenna is ideal for amateur radio enthusiasts, repeater builders, emergency communications teams, and fixed station operators who need reliable operation across two of the most popular ham bands. Its robust construction and broad VHF/UHF coverage make it a trusted choice for both everyday use and critical communications scenarios.

## Questions & Answers

**Q: How does this connect to the support pole? What diameter pole is needed?**
A: The antenna comes with a 1 1/4" support tube which the antenna itself mounts in.  The support tube has two u-bolt clamps to mount the support tube to the mast.  The clamps will work on the mast tubing of 1 1/4" to 2" in diameter.

**Q: What are the dimensions of this antenna when fully assembled? I may need to deploy through a window.**
A: Approximately 60x3x3 inches.  Would not recommend indoor use.

**Q: Does this have pl259 type connector?**
A: Yeah, the x50a is a so-239 ....the x50n is a n type connector ...use no less that rg8 feed line ....I recommend lmr400 which is what I use ....73's

**Q: Will this work in the 450-470mhz range?**
A: Yes it will, it works in the 70cm bands (420-450) MHz as well as the 2 meter (144-148) MHz bands. It's a great antenna with good gain and is really well made. Hope this helps.
