Please excuse a novice's timid hand raised in the
back row, but...
Ive got an accumulation
of television stuff in the workshop and got to wondering
if any of the various video signal amplifiers can
be used for 2.4ghz? I seem unable to find any specs
on them. I'm hoping they might have anywhere between
200 and 500ma power. They have low voltage wall
adapters and I could replace the coax connections
with rp-sma.
I have seen 500ma signal amps
on the net, but for 120.00 I thought that I might
just experiment with the ones I have to see if they
are of any use at all. Can I do any real damage
by trying? Is it certainly a waste of time? Is the
freq range of these devices absolutely fixed? Or
is this range something that can be tinkered with
given the basic components inside?
Thanks
for any advice.

Given the option of replacing a 2dbi omni antenna
with a 7dbi omni antenna on a wireless router, or
putting a small -let's say 250ma- "booster" between
the existing antenna and the router, which is preferable?
For the sake of argument, if after the math is done,
(I have not done it), we've gained exactly the same
dbi with the amp as would have been gained using
a bigger antenna, is there any difference between
these improvements?

a little more searching may have answered my question.
the amp needs to be bi-directional for wlan xmit/receive.
tv/video boosters are not, apparantly. but would
not many newer versions be bi-directional since
so much media is becoming interactive?
