XM Signal drop off

[empulse]

<p>I have seen this topic/question in some posts lately (post i have viewed lately).&nbsp; I thought i would share what i have found.&nbsp; Ever see&nbsp;a Cellular looking tower, may even have all sorts of&nbsp;omni-directional or quadrant antennas on it? (just picture a cell tower, k)&nbsp;Now, notice the cylinder/disc/drum like things attached on the sides of the tower? Those are microwave tranceivers (they transmit and receive data).</p><p>They transmit @ either 2.4 (like your wireless router), 5.8, 11 ghz (even higher frequency), but so does&nbsp;XM.&nbsp; They transmit in a straight line, and if you are directly underneath there x-mit path, boom no signal, but when you are driving because of the buffer in your radio you probably won't notice it.&nbsp; But as tower density becomes more, and more signals are criss-crossing above you, i would guess it would get worse.&nbsp; I have several near my house, and have parked my truck near, and up to a mile from the x-mitter and everytime my signal cuts out, when i am underneath the&nbsp;transmit path.&nbsp; I would imagine in major citys this problem becomes vastly greater.&nbsp; </p><p>I know. boring. but this is a major reason why. and yes i have too much free time.</p><p>If only this post touches one kid with cancers life... i will have not lived&nbsp;a wasted life.</p><p>&nbsp;&nbsp;</p>

Not boring at all.&nbsp; Interesting (to me) topic.&nbsp; That explains a lot.&nbsp; <a href="http://glasnost.itcarlow.ie/~net4/kirwans/bband.html" target="_self">This</a> should only make things worse.&nbsp; <br />

<p>Aren't XM's repeaters mounted on a lot of radio towers?</p><p>&nbsp;</p><p>Also, my old job had a microwave transmitter to throw the signal to the tower 10 miles away, and I constantly drove in the path - I never had a prolem losing signal.</p><p>&nbsp;</p>

driving underneath wouldn't re-create the problem.&nbsp; If i drive under a bridge @ say no less than 10-15MPH i don't lose my signal cuz of the buffer in the radio.&nbsp; Same on the highway, quickly passing underneath bridges, or other interferences wouldn't do it.&nbsp;&nbsp;&nbsp;probably 3 weeks ago when i did my little test,&nbsp; i do remember the closer you are to the tower the wider the area of disruption.

I hate driving an underpass in traffic and losing signal. It always happens right before a huge joke and you hear the laughter afterwards.
