Interference to your 3G and 4G services?

Comments Off on Interference to your 3G and 4G services?


newBetter Data with our New Bandstop Filter

With more and more of our clients having problems with LTE and 3G interference from different RF sources, this new filter helps prevent any interference from the frequency band 1983.1 – 1990 MHz.

Interference Prevention with Customisation

We can customise any Passband and Stopband for your case with 30 to 50 dB rejection suiting your needs. Normally 30dB rejection is adequate in most cases, meaning that the interference is supressed to at least 20 times lower in power. This will improve voice and data significantly, bring more traffic, more revenue and happier customers in the network with improved LOYALTY!

Invisible LTE Antenna for ALL frequencies

December 29th, 2011
Comments Off on Invisible LTE Antenna for ALL frequencies

Our Invisible Antenna  has recently been upgraded to cover all 4G/LTE frequencies, making it a truly global choice for all LTE systems.

Invisible LTE Antenna (datasheet)

Why is it Invisible ?

Our invisible antenna is one of our best selling items. This is mounted from above the false ceiling and only the ‘smoke detector’ shape is seen by the users. Making the antenna invisible

How does it help Data service for 3G / 4G?

This actually allows you to have the dipole below the ceiling for maximum Data performance, while it is so low profile that does not make users think that there is an antenna. Since the dipole is below ceiling, it will not be blocked by builder materials. These materials are often made of metal which reduces available radio signal strength and caused reflection and difraction. By using the Invisible Antenna, the maximum Signal to Noise Ratio and Signal Strength are acieved to allow best  Voice Quality and Data Throughput.

Why is the Invisible Antenna best for 3G / 4G?

We have now upgraded this Invisible Antenna to support 700 MHz to 6000 MHz, covering the 4G / LTE frequencies. By using this antenna, the building is future proof. If an upgrade is required you are ensured that the antenna can continue be used to support the next technology.

Variable Power Management for LTE

Comments Off on Variable Power Management for LTE

LTE 4G variable attenuator

When it comes to precise control of power levels, DragonTECH has the best LTE solutions.

Systems like optical RF transport systems require flexibility for the site enginer to be able to finetune power levels, and yet high precision is required. Not to mention that it needs to be very reliable so the power levels stay exactly the same after testing and commissioning.

Consider the Variable Attenuator LTE 0-3000MHz, contact us for more details.

Comments Off on I bet you will never forget to bring that Jumper Cable along

3 way splitter with JumperWe will give you Spliiters with Jumper Cables Affixed!

We have a new series of Power Dividers that comes with the necessary Jumper Cables. The length and connectors can be customised.

This alleviates a lot of connections on site for a faster and easier implementation. In cases where clients are charged according to the BoQ this new idea greatly reduceds install cost.

We can customise Jumper Cables and RF components for you.

DragonTECH QMA Connectors

September 5th, 2009
Comments Off on DragonTECH QMA Connectors

Recently a lot of customers asked for QMA connectors and jumper cables.

Save MaQMA connector crimp straight typeting Time

QMA or Quick Lock SMA connectors enable fast and easy matings. It is a good alternative to SMA dna N type connectors. It uses a Snap-on mechanism to allow matings to be fast and secure. It is secure through a chamfer with a click sound during a positive mating.

The DragonTECH QMA connectors are tested against shock and multiple matings. Below is the straight type.

Save Space

QMA connectors have a lower space requirement because the use of a wrench is not needed here. In addition, the small size and the distance between connectors can be optimised on the equipment panel.

Below is the DragonTECH QMA Righ-angled connector.

We will supply Jumper Cable Assembly with RG223 cable.
