High-Power 2m / 70cm Base Antenna

Diamond X-510MH 144/430MHz Dual Band Base Antenna

High-gain 2m and 70cm vertical with 350W maximum power handling, 8.3dBi gain on 144MHz, 11.7dBi on 430MHz and an SO-239 antenna connection.

The Diamond X-510MH is a high-gain 144/430MHz dual-band base antenna designed for fixed installations where strong omnidirectional coverage and increased RF power handling are required.

At 5.2 metres long, the X-510MH uses a multi-section phased vertical design to provide 8.3dBi gain on 144MHz and 11.7dBi on 430MHz.

The MH version increases maximum power handling to 350W and uses an SO-239 UHF female connection, making it particularly convenient for installations using coax terminated with a standard PL-259 plug.

POWER
350W Maximum

Increased power handling for higher-power VHF and UHF fixed-station installations.

144MHz
8.3dBi Gain

Three-section 5/8-wave C-Load phased vertical arrangement for the 2m band.

430MHz
11.7dBi Gain

Eight-section 5/8-wave C-Load phased vertical arrangement for the 70cm band.

FEED CONNECTION
SO-239

UHF female antenna socket for use with a PL-259 terminated coaxial feed line.

X-510 High-Power Version

350W Power Handling

The X-510MH shares the same 5.2 metre overall length and high-gain phased antenna format as the X-510N, but raises the maximum power rating from 200W to 350W.

It also substitutes the X-510N's N-Type female connector for an SO-239, making the MH version better suited to installations already standardised around PL-259 terminated coax.

Antenna Design

High-Gain Phased Vertical Elements

The X-510MH uses stacked 5/8-wave sections to concentrate its radiation pattern towards the horizon, providing high omnidirectional gain for fixed-station operation.

2 METRES
3 × 5/8-Wave C-Load

Phased vertical arrangement providing 8.3dBi gain on 144MHz.

70 CENTIMETRES
8 × 5/8-Wave C-Load

Eight phased sections provide 11.7dBi gain on 430MHz.

Fixed Station Performance

Designed for Wide-Area Horizontal Coverage

The combination of substantial physical length and phased vertical elements makes the X-510MH particularly well suited to repeater access, local and regional simplex operation and other fixed-station applications where low-angle omnidirectional coverage is desirable.

Outdoor Construction

FRP Fibreglass Outer Shell

The antenna elements are enclosed within a weather-resistant FRP fibreglass outer shell for permanent outdoor installation.

Diamond specifies a rated wind velocity of 40m/s and a compatible mast diameter of approximately 30 to 60mm.

Installation

A Full-Size 5.2 Metre Base Antenna

The X-510MH is a substantial fixed-station antenna. Check available mast height, surrounding clearance and wind loading before installation.
