Wifi Jammer MK2

Intro: Wifi Jammer MK2

This uses the same 2.4GHz AV transmitters used in the first jammer, but this time they run through a 4 watt amplifier.
Battery capacity has also been increase using 3.7 volt phone batteries.
The main reason for building the MK2 was to have more control over what part of the spectrum I am jamming. So instead of jamming all channels I can now select channels individually.

Andrew, Hi.
I have watched all three of the videos you have uploaded about making a WiFi jammer and even for a total electronics newbie I think I could replicate what you've made in your first video.
I've got some questions - if you'd be so kind as to help me out. In particular in the video you made of the Mk2 jammer, I did not see how you connected the cable from the antenna to the 4w amplifier. The cable/wire is quite thin so I'm guessing you stripped back the outer wire to expose the inner core and then the outer core/braid shield; I guess you twisted some back so you've then got the inner wire for the antenna and the outer wire goes to ground - on the 4w amplifier you used ... how did you connect all three antennas to that amplifier circuit board. Secondly, you mentioned in your first video of using LMR80 cable. Not even Google has heard of LMR80. Closest LMR to 80 I can find is LMR100 cable. If I need to use LMR cable, what should I look for? Could you also tell me if this 4w Wifi amplifier would be ok to use (link below ...)
Thanks

Can I use this model to transmit and recieve video from some camera..
And how I can do that..
Pls if someone could help???

Whay 2.4GHz wifi analyzer software are you using please Andrew, ? & is it free off the net.?

[ÁdámS66]

What kind of wifi analyzer do you use?

Presumably then everyone here has considered that most of the first world now runs on 5Ghz WIFI and have been for some years now??

That's not all that true as far as residential wifi goes. I won't pretend I know anything about business provided WIFI. Go ahead and look at your Wifi specs. If it says 802.11b, 802.11g, or 802.11n, you are sporting the 2.4Ghz spectrum yourself.

If you have 802.11ac or 802.11a, then you are using 5Ghz WIFI.

I looked at all my neighbors residential wifi types and did not see any 5Ghz. If I am not mistaken, 5Ghz is more common in the newer phones.

How do I gain access to the full links you have referenced? Thanks

To connect all the aerials, do you simply solder the signal part together and all the shielding? Then all that goes to the amplifier? I just tried connecting all the aerials (no shielding) and there was no signal coming out.

I will watch this a few more times and build one as I am paranoid about cameras in rental rooms, etc. Any comments on the "charging port" that you mentioned? I ddi not see this.

I sort of do not know what I am doing so I will no doubt screw up several along the way.

Thanks.

That is quite impressive. Do you think you will ever begin constructing them and selling them for a small fee?
