  1. Here's what they say, They do use the term "vertical" and "Horizontal" polarization, but also say it doesn't matter????? http://www.l-com.com/multimedia/manuals/M_HG2409PCR-SM.PDF
  2. The install manual says for vertical polarization cable should be exiting from bottom or top. For horizontal polarization cable should be exiting from left or right of the antenna. I will be mounting it, of couse "on edge" not laying flat or flat against a ceiling. In my application, does it matter how it is oriented?
  3. Thanks to all. I have ordered up 2 of these: http://www.l-com.com/item.aspx?id=21787 One more really basic question. Do I use 50 ohm cable if I must use an extension? I lied....one more basic question....for my application, do I mount them horizontally or vertically?
  4. I see now thr polarized one is 65* both horizontal and vertical....that should be plenty wide enough.
  5. Ok, I made up two of the windsurfers and I do note a marked improvement. I now have no bouncing (cutting out?) of the picture and no bands of snowy white noise. I still have occasional white horizontal lines (frequency interference?), but even that is lessened. This is with the 10" antenna extension cable attached and the stock, what, maybe 1dB - 2 dB gain short antennae??? There was a difference whether I installed neither, one or the other, or both windsurfers, with obviously both installed being the best. So what is your advice? Two of these 8 dB gain? http://www.l-com.co
  6. Is 2 of these this what I need? http://www.l-com.com/item.aspx?id=21787 What's the difference between right hand and left hand? Which do I need? Are there any smaller units available? This is the correct connector right? (based on the receiver and transmitter in the first post link) Is there a problem if I use an additional 10 foot extension to get the camera antenna routed inside the trailer, thus eliminating two aluminum skins and aluminum framework? This would give the signal a path through one wood cabinet face, two panes of glass and one pane of plexiglass.
  7. What are circular polarized aerials? Can you point me to some online? Any small ones for my particular need?
  8. Thanks, Terry, I thought that might be the response I got. I did read up quite a bit about directional patch antennas. (Not that I understand too much of what I read) When I go shopping online, all I see are pretty big ones designed for long distances or large areas. I also found forums where RC'ers made their own small ones for airplanes and the like, but the parts list and construction directions assumed the reader knew A LOT more than I certainly do. Since I only need to send the signal 45', what is commercially available that is small, not unattractive and unobtrusive? Obviou
  9. I hope you folks can help. This isn't an RC issue, but it seems to me that the forum members here understand the little 2.4 GHz systems better than some other places. I've been lurking and TRYING to keep up. I have very little understanding in this area, so be gentle, please! I have a 30' Airstream travel trailer on which I am mounting a backup wireless camera. It is about 45' from camera to monitor. I pass through a lot of aluminum, wood and glass between. This is the system I have. http://www.4ucam.com/Wireless-Backup-Camera-7-inch-Monitor-9901-Color-RV-Cam-Truck-Trailer-Rear-View
