The Satellite radio antenna is one of three basic hardware components youll need to receive those digital audio streams from your favourite Satellite radio service provider.

Although both providers offer similar services and use similar technologies, the associated hardware, including the antenna, is designed to receive either XM or Sirius programming. We have read articles where listeners have interchanged antennas with some success but it is not recommended.

The antennas task is to pick up the signals transmitted from the Satellites and terrestrial repeaters scattered about the u.s., with a reliable receive performance. In order to achieve this, the antenna must have an unobstructed view (line-of-sight) of at least one orbiting satellite. In urban areas where buildings and terrain are likely to block the Satellite signal, the antenna picks up the signal broadcast from the terrestrial repeaters instead.

To ensure an uninterrupted Satellite radio service, both Sirius and XM provide recommendations for ideal antenna mounting locations. Furthermore, many home and plug-and-play Satellite radio units offer special antenna aiming screens within their menu options.

With a rapid advancement in Satellite radio antenna technology, XM and Sirius are able to offer their listeners a wide range of antennas, accessories and flexible installation options.

So the question: Which Satellite radio antenna do I need? Although taste can play a small part in choosing the right antenna, the decision largely depends on whether you want to listen to Satellite radio in your vehicle, on your boat, at home or indeed anywhere! one thing you can be sure of is that all Satellite radio antennas available today are neither too cumbersome, nor impose limitations on your vehicle, boat or homes aesthetics.

If you're like me, you know about back pain. All about it! I don't get it often, but when I do ... boy do I know it's there!

The most common cause of back pain in North american adults is sciatic pain. So in this article I want to tell you about sciatica, look at a possible cures for you, and make a personal recommendation.

OK ... sciatica treatment. Let's start with a quick description of the problem.

You have nerves running all through your body, which feed huge amounts of information to the brain and are absolutely critical to your functioning. Your biggest nerve is the sciatic nerve. It is attached to your lower spine, runs across your buttocks, then down your legs as far as your ankles.

When that nerve gets irritated or pinched or rubbed up the wrong way you feel pain. Although pain generally is notoriously hard to pinpoint, the pain from an upset sciatic nerve is usually felt in the lower back, or at the back of your leg above or below the knee.

At times it will be excruciating. (Do I sense you nodding in recognition?) Often it is dull and troublesome. It can be very, very persistent.

So, what can you do?

Normally, the first reaction is rest. And a couple of days of rest can be helpful. Surprisingly, however, resting for any longer only tends to make the pain worse. And none of us have that much free time anyway. So, rest is not the long-term answer.

There's got to be another way. And there is; do more exercise!

Either do strength-building exercises, that will make your abdomen and back muscles stronger, and give better support to your lower back.

Or do stretching exercises. These will gently push and pull on tight, inflexible muscles that may be the source of the pain, and in a few days the pain will have gone. Keeping up stretching exercises will give you quicker recovery and work to help you get no future flare ups.

Or, equally effective, do light aerobic exercise. Things like walking and swimming. These sort of exercises will move fluids and elements around your body, building a better healing environment for you, and will also release your natural pain killers, the endorphins.

So, for some people, exercise and movement is going to help sometimes.

If that fails, over the long term, however, I recommend you look around for a well qualified doctor who is a sciatica specialist.

Be demanding on yourself as you look. Choose the best specialist you can find. Don't shop around for the cheapest deal. Ask questions until you find a good practitioner. Someone with years of experience treating sciatica, who is a surgeon and, if possible, teaches medicine at a school, would be ideal. Sciatica treatment is hard to get right, and unless you work hard to find a well-qualified specialist your treatments are likely to be short-lived.
