hi i used 3 antennas as i am using a 4 watt amp and wanted to spread the load. i have also experimented with a 4 element yagi and a cloverleaf to make this more directional.
i am going to do the same. How did it workout for you? will use helix antennas. so the space around my caravan will not be flooded with bluetooth speakers next summer. At least i am now able to be so kind shutting them off the air after 11pm ;)
Hi MT thanks for the comment I have a cisco made yagi and it performs about the same as a double biquad. To make a yargi though you would need a drill press.
do you think its possible to build a jammer by using a vco at about 2.45 ghz and a second vco to modulate the first one with plus/minus 50mhz and sweep from 2.4 to 2.5?
I have seen a few videos showing this or something similar. They never show how they perform though. Maybe a yagi PCB mounted inside may work. May look at it and make a video comparing the performance, standard can v yagi can. Might be interesting what do you think?
Can you please add a link to the Amp that you used in the description? And did you simply wire all 4 outs of the transmitters together to the 1 input of the amp?
Hello, Can you please tell me about 2.4GHz AV transmitters? What kind of receiver is used, and what is the range. Is there any user manual or tutorial for this? Thank you in advance.
wifi jammers are illegal in australia lucky i found your videos as my neighbour has been jamming my cb radio with a faulty modem i hoping if i jam his modem permanently he will replace his faulty modem.
thank you, absolutely brilliant !! I'm just trying to figure out how the channels are supposed to be wired haha. My build will jam everything instead of selecting. could you please explain how i wire it to jam everything at once ?
Hi Andrew ! I am 7 years late in making your jammer and I find that the 4x TX6729 's I have purchased appear to have the positive and negative leads reversed? I say this because another project I found on TH-cam has the exact same Tx6729 17/06/01 release as I do and wires them as I have said ! as the boards have no markings will I cause damage by wiring them incorrectly ? Very interesting some of the projects you demonstrating ! Thank you !
Building something like this and understanding how it works helps you to understand 2.4ghz and its limitations. Of course like anything it can also be abused. Much like the TV-B-Gone, the little remote that can turn off 99% of TVs. Its ok to play around with in your own home but to take it out side and annoy Joe public is another matter. :-)
yes thats how i did it. If this was an antenna build it would be a bad idea to connect them like this, (to much loss). But as this is just a jammer (making as much dirty noise as possible) its ok.
Another small and stupid question, the ground of the four 2.4 antennas are connected together? This ground should then be connected to the amplifier ground input? Thank you

any chance for a 5ghz tutorial?

any transmitters
4:23 it looks like it's polarity is reversed, is it TX6729?

Thanks for that - is there an advantage in having 4 output antennas vs one in this situation?
a quick question.
all the tiny 2.4 video TXS Antennas are conected to each other , and all goes to RFIn of amplifier?
+George Chatzisavvidis Hi George yes that,s how I did it.
+andrew mcneil something else.. the amplifier works for 2.4ghz Data ? is there any problem using it with audio visual?
+George Chatzisavvidis Like a FPV setup? If so then no there is no difference it's all just data,
+andrew mcneil i think you have to use splitter combiner wilkinson, and a attenuator
+George Chatzisavvidis Is that to use the amplifier for an FPV setup? All an attenuator does is limit the power down the line.
Can only find AV transmitters with 3 channels on , anyone got a link for transmitters ? Uk thanjs
thank you, absolutely brilliant !!

You can check continuity with ground with a known ground on the board but I have not come across any with reverse positive and negative.
@@andrewmcneil Yes ! I will try and do that ! the TH-cam project I was referring to is this one ---Wi-Fi tinklo blokatorius

Hi,
How are you working the antennas? Are they all joining up together into the amplifier then split out again?
This is very fine. I am trying to think of a reason why someone would want one of these jammers, however.

Indeed, and thank you. I want one, and I have no idea *WHY* I want one.
yes thats how i did it. If this was an antenna build it would be a bad idea to connect them like this, (to much loss). But as this is just a jammer (making as much dirty noise as possible) its ok.
Are all A/V TX connected to each other then connected to the amp?
Andrew, can you please specify what software you use for your spectrum anaylizer, please
Where did you get your amplifier
How it work? Ur Av transmitter has 4 channel and u can crash all 13 channel wifi?
4W :O what range does it block?
Another small and stupid question,
the ground of the four 2.4 antennas are connected together? This ground should then be connected to the amplifier ground input?
Thank you
same
Thanks andrew, any plans of GSM jammer ?
I have a working prototype on a breadboard. Just need to find some time to finish it off and work out a few bugs.
great news seen a few plans but you make it easy, lol also emp jammer??
Hi, great stuff where can i get the 4w amp from , and do you put all 4 aerial outputs into amp
Ebay and yes you can connect all 4.
Hello andrew , what the range of this jammer ?
Around 25 meters depending on the environment
What software is your spectrum analyzer ?
Here is a link to it on ebay: www.ebay.com/itm/2-4G-SPECTRUM-ANALYZER-WIFI-FINDER-WI-DETECTOR-/281088992043
shop around though as I only paid £18 for mine with free shipping.
Andrew
many thanks sir.
good tool, good vid, many uses if you know how and why lol
2.4 GHz is congested where I live, but on 5 GHz I am the only person in my street, so 5 GHz is the solution.
yo i need that can O worm
nice
