this is the style antenna i have installed in the past ...
for 2.6 ghz

for 900 mhz you want a yaggi ...

Thanks for the  link  IST

If you  have a few more minutes  I have a few questions  about  antennas like this .

The  one in your link  says it has  a female  N connector     does this  plug right into  a router like a Linksys ?     

I  did  a search  on  ebay .     The   WiFi  parabolic  antennas there all seem  to be 2.4 GHz         your link is  2.6GHz      is there a reason for the  difference ?



Thanks for the help

Edit

It looks like the  linksys  has  a small   power adapter   
I am  guessing it probably does not  use much power .

With  a JT  charger on a  battery this  whole thing could  be  put up  on a pole  or in a tree

Wow!

I will stop trying to do anything with the 2.4-2.6MHz I am picking up with my Stubblefiels coils. I was about to concentrate on the 22Khz anyway, but now, I wonder if the 22Khz is from those antennas . I betcha the wifi is what I have been picking up.

Thanks, now I can go back to real work on my joule thief and let it rain!

thank you IST for providing this info too,

no prob .. bill

gary ...


its really easy ...

i used an omni ant .. as my access point .. you can put a 1 watt rf amp on it ... 

then you can use any 2.6 ghz wireless bridge off the system ... we were able to pull 2+ mbps  no problem  over a good distance

only amping the access point ....   

the bridges we used were 500 ma units ... half watt  transmitter / reciever .. that with a db 36 on the roof you cant go wrong as long as your access point is high enough  like a 70" tower on a hill would do well ... 


ist ... 

split this up by 20 people ..  and costs go down fast ...

I found  this  on ebay

It sounds like it  does everything  you talked about .....except  using  amps .

Does it look  to you like it will do what they say it  will do ?

These  signals  are Gigahertz   
I guess you  could be picking  up  a lower harmonic  of them  .
If that is  what is happening     your  equipment   is probably not  fast enough to see the  true  frequency

Oh, so they are!

Well, now I don't have a reasonable excuse to stop anymore!
So then, I will keep on going ! 

I like the spike nature of them even though they are not very big. I keep trying to use the spikes. In a JT the spikes from the basic jt toroid are not hundreds but because they are in a toroid (I assume that is the reason) the multiplication of volts is very high. Yet, I am not getting more than 100mv from it.

Of course that is 10 times without any inductors if you count the stubs as inductors....so I should be incouraged not discouraged.
I want more!!

What I really want to do is make a toroid that is the inductor like the stubblefield. I just haven't figured how I want to stick it into the ground.


Gary,
Thanks for noticing and mentioning my mistake.
