If you have signal problems with the typical low-power 15mW systems, you
can always get something beefier at both ends. You can get nice 300mW
systems and cards from places like Ubiquiti for not much more than
department store router prices. see http://www.ubnt.com/ I have one of
their 300mw PCI cards and a now discontinued 300mW AP card.

I am now convinced that ethernet over power has reached an adequate
cost/service ratio, and are the best way to go.

Powerline networks are up to 200Mb commonly, and you can get a starter
kit with two or three, depending on brand and model, for about $150.00.

A combination of ethernet over power, and a meshed wireless set up from
open-mesh is the best of both worlds.

Good Luck!

When Wireless-n was approved I bought a cheap Rosewill AP from Newegg and a USB
dongle, and a PCI USB card so I could learn ad hoc networks. I am in an 1895
three story Victorian house, my computer room is on the 2nd floor. I bought this
equipment because it was cheap and I could return it. Haven't yet.

I work all over the house, on the porch, in the back yard, it's all good. My
usual workplace is a recliner in the library, in front of the TV. Get 100Mb or
so, not bonding, little of what I do needs speed, but dead reliable.

I hope this is similar enough to be useful.

Have you thought of a signal booster and antennae?

Note: Antennas can be direct or omnidirectional and
amps can have different wattages. Have a look at
these links:

FWIW,

yes, but in time, a bend, less than recommended, would be more of a center
wire propagation than of reflection concern.

both are a consideration that all who install coax cable should be aware of.

this is true. all in design. would not be a lot of coax being sold if
it where not so made. and just think how far 2 way radio communications
would have gotten if coax was not designed for different spreads.

like gene said, more of a selling point.

you must be young, unlike gene and i.

for as for your "<snicker>", you do not get joke i was making and never
did any cb radioing in early days.

so to bring you to and understanding, in days of old, there were basically
2 50 ohm coaxes used, rg58/u and rg8/u. rg8/u had a lower loss than rg58/u
and many cb'ers would use rg8/u because it has less loss than rg58/u.

because of this, cb'ers started calling rg8/u 'low loss' coax.

as for having more rf knowledge in his little finger, that may be. but my
fingers and my brain have held more than just rf knowledge.

> {^_-} <- An RF engineer who took the time to get to know Gene.

'tis a shame you have limited yourself to just rf. as you sound like you
have spent too much time around transmitter stations. ;^P

so, go ahead with your reply, i am thru with 'off subject'.
