Milestek-Blog

The bulk of the HDMI extender devices we look at here on the MilesTek blog utilize high-quality, but inexpensive Ethernet cables to give users an enormous amount of welcome flexibility in their AV set-ups. But we also provide HDMI extenders that run over wireless connections and (as we’ll discuss here) coaxial cables as well.

Check out our HDMI Over Single RG6/SDI Coax Extender Sets — a new solution for upgrading to fully digital platforms using older technology.

The extenders can run sparkling-quality 1080p resolution signals up to 400 feet (120 meters), without losing quality, over a RG6 dual or quad shield cable. They can even extend SD-SDI signals up to 1,000 feet (300 meters). But perhaps most significantly, they are also compatible with RG6 and SDI applications.

By utilizing existing runs of RG6 or SDI coaxial cable, the extenders eliminate the need to install new runs of cable. This both lowers costs and simplifies installation (especially if your existing coax runs are difficult to reach or would require minor construction to replace). And the extender’s application compatibility allows it to connect directly from your source device (say, your DVD player, laptop, or cable/satellite box) to your display device (high-def TV, projector or computer monitor).

Taking this technology one step further, we also designed it to allow signals from two input sources to transmit to one remote display for improved functionality. Plus, a cascade port is located on both transmitter and receiver, making it possible to expand signals to multiple remote receivers.

Important technical notes:

– The coax ends need to be terminated with BNC connectors. Do not use an F-to-BNC connector adapter.

–  As we mentioned above (it’s worth reiterating, for reasons that you’ll see below), the extender should not be used in conjunction with connector adapters, AV receivers/signal processors, switches or splitters between the source and display device. Instead, we designed this extender specifically to work directly between the original source device and the display (the extender will basically burn out in just a couple days or weeks if you do, leaving you without any picture at all).

– 75-ohm broadband coax cable must be used.

– The handy starter kit package includes a transmitter, a receiver and a remote control for switching between inputs.
