HDMI wireless extendersYes, everyone will be focused on the dazzling 1080p high-def brilliance coming from your TV. No, that doesn’t mean they won’t notice all the holes you drilled through your walls in order to connect your HDMI cables.

Our new plug-and-play HDMI wireless extenders make A/V system setup easy and cable-free — without tearing up the walls around your entertainment center.

Boasting performance speeds of 300 Mbps, the wireless capabilities can extend up to 30 meters, while replicating high-definition visuals flawlessly. The extenders also feature full digital and analog audio support at transmission.

Unlike many other HDMI wireless devices, our extenders can transmit source signals through walls, which you don’t need to rely on direct line-of-sight for the connections to maintain top quality. Instead, you can set up the A/V system that best fits your needs, and design viewing rooms around comfort and ease instead.

This, of course, is ideal for multi-room installations. Imagine the possibilities:

  • Restaurants, bars, or clubs with multiple TVs
  • Sports viewing parties
  • Art displays
  • Trade show demonstrations
  • Training centers
  • Divided office environments
  • Temporary setups where permanent drilling marks are undesirable
  • Homes with antique or non-drillable walls

It’s all made possible by cutting-edge technology that is bursting with new features, including:

  • Auto-tracing, thanks to a smart antenna
  • Real-time, visually lossless HD compression
  • Indoor transmission extension up to 30 meters (98 feet)
  • Full compliance with IEEE802.11n draft 2.0 and IEEE 802.11-a standards
  • Compatibility with HDMI- and wireless-compliant devices
  • Compatibility with HDCP 1.1/1.2-compliant devices


In other words, the wireless HDMI extenders makes it simpler to customize your AV system around your unique needs. The units are small, sleek, and attractive, and represent the future of plug-and-play AV devices.

4x4 HDMI Over CAT5E/CAT6 Matrix SwitcherMore flexibility. More capabilities. Less expensive. Meet our new (deep breath) HDMI over dual CAT5E/CAT6 4X4 matrix switcher-and-receiver sets. It’s a mouthful—but the sets are bursting with new capabilities that can vastly improve your AV setup.

Let’s take a look:

In general, running HDMI distribution over CAT5E and CAT6 cables is a great way to hold down costs and give AV systems the flexibility needed to meet their customers needs (without, of course, sacrificing the high quality that comes with HDMI). They’re ideal for any environment where multiple AV displays come in handy, like corporate training sessions and trade shows. And while HDMI cables provide extraordinary signal clarity, they’re more expensive than CAT5E/CAT6 cables, and cannot maintain high quality over long distances (usually around 50 feet).

Instead, running HDMI signals through, say, one of our single CAT5E/CAT6 splitters and receivers can extend a signal up to 164 feet to as many as eight different HDTV displays. Imagine the possibilities.

Our new dual switcher/receiver sets simply expand these improved capabilities. Boasting unmatched flexibility, the new switcher/receiver sets can connect high-def AV signals from any of four HDMI sources (like blu-ray players, computers, video game systems, etc.) to any of four remote displays. All you need is a single HDMI cable, or two CAT5E/CAT6 cables.

The sets are full of new features, including:

  • The sets allow any HDMI display to view any HDMI source at any time
  • Any HDMI source can now be displayed on multiple HDMI displays — at the same time
  • The 4×4 matrix switch includes: four HDMI inputs and four single HDMI or double CAT 5e/CAT 6 outputs (although only one output format can be used at any one time)
  • The receiver units include: One HDMI Output and two CAT 5e/CAT 6 inputs (four receivers Total)
  • A vast transmission range, including:
    • 40 meters (130 feet) of 1080p resolution when used with (2) CAT5E/CAT6 outputs
    • 15 meters (50 feet) of 1080p resolution when used with HDMI output
  • Each input includes an infrared emitter, enabling remote-control access of the source device
  • Display inputs can be switched using the included IR remote control, as well as through RS232
  • Support for high-def resolutions at 1080p high-def resolution.

In other words, they make extraordinary technology even more useful. Check out our complete line of HDMI extenders for more information.

Triax Patch Panels Explained


Last week we highlighted some of the benefits of our triax cable systems, compared to twinax cable systems. But it’s also important to understand how they connect to the big picture, and how they can work together with the help of triax patch panels.

If you’re unfamiliar with patch panels, think about a telephone switchboard: one cable connects the operator to the switchboard, a mass of cables connect the board to the community (“Let me patch you through.”).

Patch panels make it easy for technicians to quickly and easily redirect a signal path, without needing a bunch of dedicated switching equipment. And they add flexibility and organization, making it easy to test signals and optimize the cable system.

These days, you’ll see patchbays in any setting where you have a wide variety of A/V inputs and outputs (microphones, cameras, instruments, sound equipment, soundboards, amps, etc.) that need to be organized and controlled in order to get the desired output, like recording studios. Instead of wasting time organizing cords or installing a temporary set of cables each time the band sets, a good set of patch panels simply make it easier to plug in to permanent cables, get right to work and start making music.

Since triaxial cable systems are most often used for visual applications like camera-CCU connections, triax patch panels come in handy anywhere commonly used for filming. This includes TV or movie studios, of course, but also places like sports arenas and government buildings that are common spots for news crews. Triax patchbays make it easy for TV crews to plug in to permanent triax cables, stay connected to their truck outside, and start shooting—without having to wire in a massive network of cables throughout the building.

We provide multiple patch panels and accessories, including:

• TRB and BNC distribution panels
• Standard and subminiature patch panels
Cable assemblies and looping plugs
Racks, cabinets and shelving

… plus a full catalog of patching accessories, including:

• Standard twinax/triax patching
• Front-loading modular panels
• Subminiature twinax/triax patching
• Standard twinax/triax looping plugs
• Subminiature twinax/triax looping plugs
• Standard coax patching

Twinax Cables

Basically, twinaxial cables feature a two-conductor twisted balanced wire line and a specific impedance (at MilesTek, we provide both 78-ohm and 124-ohm twinax cables and accessories), plus a shielding braid around both wires. They’re similar are similar to coaxial cables, but, of course, with two inner conductors instead of one.

This construction matters for a couple reasons:

  • It lowers cable losses.
  • It provides protection against ground loops and capacitive fields.
  • By using more copper wire in a more tightly-weaved braid, it improves coverage to 90 percent (triax cables also benefit from this design).
  • It protects against low-frequency magnetic noise that passes through the copper braid.
  • By twisting the two balanced-signal-carrying wires, it makes it possible to cancel any random induced noise voltage pickup.
  • With two dielectric fillers under the braid, it allows the the signal pair to be separated away from the braid, lowering the leakage capacitance to ground.

As a result, twinax cables are a cost-efficient, effective option for short-range, high-speed differential signaling applications. However, the cables begin to lose their effectiveness around 15 MHz, after which transmission losses begin to increase. Therefore, they’re best suited for low-frequency digital and video distribution systems like connecting MIL-STD-1553 bus and stub devices.

Triax Cable

Triaxial cables are essentially coaxial cables with an added outer copper braid (basically, a shield), which is insulated from the signal-carrying conductors. The shield is grounded and passes both ground loop and capacitive field noise currents away from the signal-carrying coax.

Triax cabling can also be used in “driven shield” applications, where the inner conductor and the first braid are driven in parallel at the transmitting end, and work against the outer braid that’s insulated above ground. The inner braid is left floating at the receiving end, providing a sort of “Faraday shield” (which protects the internal conductors from electrical noise) between the inner conductor and outer braid.

This design is full of benefits, including:

  • Bandwidth and rejection of interference are increased.
  • The extra outer copper braid acts as a shield, protecting the enclosed coax conductors.
  • The grounded “shield” significantly improves signal-to-noise ratio (compared to, say, a standard coax cable).
  • The “Faraday” shield, significantly reduced the cable’s distributed capacitance.
  • Cable losses and loading are also reduced.

Triax cables are effective for a broad range of applications, including high-frequency transducer data systems and precision low-current measurements. Also, the outer braids are useful as a low-impedence transmission line.

Both of these solutions are available in MileseTek’s new Mil-Aero/RF Interconnect Solutions catalog.
