![]() In article -did-not-set--mail-host-address--so-shoot-me, Lawrence Statton N1GAK/XE1 wrote: But be sure to bring a hefty brick along to create the opening in the first place ![]() The OP's dilema was that the window COULD NOT open, and therefore some way to pass RF through glass would have been Useful. A lot of modern buildings have glass windows which not only cannot be opened, but which have a "low-E" (low thermal emission) coating on the glass. This is (I believe) a very thin layer of vapor-deposited metal. Its RF attenuation is considerable. Some years ago, we had our house windows (1960s-era glass) replaced with new ones using a low-E-coated glass. A previously-workable signal path for 802.11 signals, which got to the back of the house from an access point in the garage by going through the garage door and a couple of exterior windows, suddently became quite unusable - I had to install an additional access point to cover that part of the house. The more obviously shaded or reflective the glass, the more of a problem for RF transmission or coupling this stuff is likely to present. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |
