Any tips then on how to prevent this Karnaugh?

thanks guys, will now move this issue onto its own thread, it needs a lot more investigation, since I haven't heard anyone with a mywi antenna mention lightning arrestors yet, it seems the installers have been very irresponsible.
(although I can take full credit for my blunder)
 
Lightning protection for a direct strike is not possible with off the shelf stuff.
A lightning bolt coming down from a 1 or 2km up is not going to be bothered by a lightning protector. The protector is there so that you can claim from insurance.

A lightning protector or surge arrestor will help if you're close to a ligthning strike, but it's not guaranteed. The electric field around a lightning bolt is enough to fry a modem incl. the port it's connected to on a telephone line.
 
yeah and there just is no switching device faster than the speed of light [:p] thus theres no way to divert all that current away from your modem. basically put up a bigger pole next to your mast. Ground that pole very nicely. This way the lightning is likely to go for the higher pole. Or find some other way to de-wire the link from the lightning entry point to your AP.
 
you know, if I can create a product that reacts faster than light to divert the ligtning or cut off before it hits, I'll be a millionare

thanks for the idea greedyflyza!

You'll also be a millionaire if you can invent a way to harnass the power of a lightning strike ;-)

Probably not a good idea, you'd be dead [;)]
 
Gonna get me the following parts to start assembling in about 2 months time.

Senao SL3054CB3+ Bridge
22dBi grid with feed plus a mounting pole.
the cable's
UPS I have. Works out to just about R2000

Now just to install it without the wife noticing... [8D]

My antenna is about 1.5k alone *sigh*

Hell, my gran on a scooter with a memory stick is faster than Sentech's MyWireless!
 
What antenna are u installing noone..... what distance are they predicting you are going to get???
 
This seems to be avery intresting idea, however, from the site, I am batteling to find out the encryption models etc that are being used ?

Interesting article on myadsl homepage - ICASA GETS TOUGH ON WIRELESS NETS. Icasa can't even keep their own house in order nevermind keeping up with change - how will they regulate wireless nets.
 
okay checkit.... would you take on 100000 people of the public and get slaughtered, or would you rather either a) make it legal like in all other 1st world countries, or b) not regulate it like they do telkom

i'm installing a 10dbi 120 degree sector antenna, reason why is because of where I'm based. Would be optimal.

I reckon I'd at LEAST be able to cover 10km no problem, however, if you have a directional antenna and LOS you could easily connect to me up to 20km away. Depends really I guess

Well i am in bryasntone on top of the hill and should have my radio up and running tonight.

200 mw - Senao with 18 dbi Omni.

Should be able to connect to my from anywhere up to 10 kms. I will also be puting up a flat pannel 28 dbi facing north. this should get 30km with out a problem. can anyone give me the GPS locations.

Keep Surfing
 
Does anybody know what the limit for EIRP (Effective Isotropic Radiated Power) is in South Africa. How would I work out EIRP depending on the hardware I have, I know it involves antenna gain and the power of the access point.
 
AP Name and channel ... will see what I can see this evening ;-)
