Whenever I need to buy new kit this is the place to go. Wendy and her team have excellent knowledge of the equipment they supply, access to information from manufacturers about the kit and an attitude to genuine customer service that is not often found in today's globalised corporate world. I have dealt with all the main UK broadcast suppliers and buying from Wendy's is by far the best experience.

Digitally Tuned Diversity Antenna Distribution Module DADM226-DT-MK2-P designed to offer the solution specifically in crowded RF Spectrum to the antenna distribution requirements.
Custom designed for where the weight and size matter without sacrificing performance.
Digitally Tuned (DT) Diversity Antenna Distribution Module DADM226-DT-MK2-P is a custom design, which offers the solution specifically in crowded RF spectrum to antenna distribution requirements for portable sound bag, cart, and trolley applications with improved RF performance. Narrow-Band RF Filtering provides utmost protection against interfering, unwanted-dirty RF signals and maintains robust RF integrity.
Designed for where the weight and size matters without sacrificing on performance.
The DADM226-DT-MK2-P covers frequency range 470-702MHz offering user selectable Narrow-RF-Bandwidth with ultra-high selective filters as well as Semi-Broad Band filters options.
There are 2-Modes of operations to suit individual applications and frequency allocations.
DT-Mode: Digitally tuned very selective RF Band-Pass filter in the frequency range 470-702MHz, tunable in 8MHz step, 24MHz window, with adjustable gain between +10dB to -10dB user adjustable in 1dB steps.
WB-Mode: There are 3 settings for the High-Pass (HPF) and 3 settings Low-Pass (LPF) filters giving combination of 9-semi-broadband filter bandwidths with adjustable gain between +6dB to -10dB user adjustable in 1dB steps.
The DADM226-DT-MK2-P has an extremely high input signal handling capacity with very low noise figure and offers an outstanding inter-modulation performance when compared to other low power devices available.
The DADM226-DT-MK2-P is an active antenna distribution system that eliminates multiple receiver antennas and provides a tidy solution for sound bags, carts, and trolleys enabling use of high-gain passive or active antennas with improved RF performance.
There are two industry standard BNC input connectors for antenna inputs which enable use of standard low loss RF coaxial antenna extension cables, and there are 2 x 6 mini-RF SMA connectors feeding the diversity receivers.
In applications requiring remote antenna powering, the DADM offers switchable active antenna powering, settings trough the OLED display menu, the RED LEDs indicating power ON/OFF status.
DC powering is through standard 4-pin Hirose type connector (HR1) between voltages 10-18Vdc. The dc power distribution is through HR2-HR5, the dc HR2 connector is user configurable as dc-in or dc-out, HR3-HR5 is dc-out only, all functions are through the OLED Menu. A green LED indicates the power-on status of the system box and the OLED display continuously monitors dc input voltage.
Audio Wireless Diversity Combiner/Distribution systems are now the first choice among freelance sound engineers, hiring companies as well as major broadcasters for all wireless microphone applications.
