In his case, he is using a directional antenna to "beam" signal to a remote link. In your case, you are thinking of increasing your signal dispersion (saturation) omnidirectionally, if I read your words correctly, and knowing what I do of your new setup. You have four ways to boost signal if your devices have trouble holding onto it, before adding a second unit (which I just did recently for someone with a "dead spot" in his house): 1. Increase output wattage at the transceiver. This is not usually desirable, as it tends to overheat these little units. Also, finding the right mix can be difficult, and just shouting more loudly may not get you the results you want (increased output also means increased noise). 2. Move the AP to a better location, where you get good signal in more places where you are likely to use it. 3. Use a passive reflector to help "bounce" signal back into your desired space which might otherwise be lost (or leaked). 4. Use higher gain antennas (or antennae, depending upon whose English you might prefer) to better distribute the available output form the device. Any or all of the above may be used to solve particular problems. You won't know if/what/where you have any until you start it up and start wandering around with a wireless device (or connect a wireless device in another room). You may be able to get good signal to this first device, but upon connecting the next, find that your "optimum" placement is across the room. That's when the above come into play. So, to more succinctly answer your question, yes, high gain omni antennas are good - where you need them. In confined spaces, or spaces which need more shaping, you may just find that they spread out too far. > IAC, the *first* wireless connection that is going to be set up > here will be when they do the install for DirecTV tomorrow.

Surely the programming grid is negligible. Mine (cable) updates every night for a few minutes, but it's dog slow (likely because of the poor quality - read: low bandwidth - of the tuner's CPU). > Jordan > > [Unrelated P.S.: Our local electric utility is beginning an > area-wide campaign of installing "smart meters."

Unfortunately, without good a arrestor, anything connected to the bus is a potential casualty. Good warning for all to heed. ;-) Thanks! -- Lewis ------------------------------------------------------------- Lewis G Rosenthal, CNA, CLP, CLE Rosenthal & Rosenthal, LLC www.2rosenthals.com Need a managed Wi-Fi hotspot? www.hautspot.com visit my IT blog www.2rosenthals.net/wordpress -------------------------------------------------------------
