Huh, having pointed all this out, I guess that makes me real freq geek.  ) |
Ahh.. yes I would say that it would
but yeah, looking at the internal construction of a Yagi it's easy to see how they're more precisely put-together than a parabolic, so I guess it's pretty easy to relate the two & their limitations that way!

It depends on the gain of the omni and the cable losses, etc. but 12 to 14dBi is probably adequate. However, it is better to jump up to the 19dBi units than to go to RF amplifiers.

Yeah, probably a 12dBi omni; I'll try to keep cable runs to a few feet if possible. I'm not sure how easy this will be, though? I'm either going to need a weatherproof case, or a 20' cable run. Hmm. It'd be nice if you could scale
down power outputs of a bridges, that way you only get what's needed for your link without polluting the airwaves unnecessarily. Oh well...

If there is a big price difference, go with 802.11b. On a distance link everything will drop to 5.5 to 1mbs anyway. "G" equipment will work, but you'll never get the "g" speeds.
|
You're right, I'll end up choosing based on price; as even 1Mb/s will be sufficient for me and I can't see myself pushing much more than 5Mb/s if I get nice connections - I might go G though, given as I'll have other bridges around for spares Just In Case.

Apologies for that, because I was asking specific questions about picking between two types of antennas, I thought it'd be best for a new thread. Seeing as I wandered off into the "b vs. g" debate, it's probably worthwhile you kicked my ass
All that said, though, I still don't know to go Yagi or Parabolic! Given the amount of trees and stuff around, and that it's probably going to help me to err on the side of more gain than less gain, I think I'll go Parabolic.
