Mussels makes some crappy wifi cantennas!

[Mussels]

Any other recommendations on stock antenna parts? I have a beauty/cosmetic issue involved as well. Which of the 3 antennas should be replaced? One? Two? All?
Friends Asus RT-AC66U, swapped stock 5dbi antennas for 9dbi.

His house has two additions with the router in a rear upstairs 2nd floor family room which is loft like in that it has a half wall with roof line pitch. The dead spot is the first addition: far outside wall, single level, TV is picture mounted. When the TV was stand mounted it picked up a signal.

Router placement is limited as phone service is included as well. The router is mostly above the roofline of the other original parts of the house. Signal issue has always been an issue to the room in question and the front part of the house.

set up a repeater, or use directional antennas from those parts of the house. no matter what you do in that situation you'll have deadspots from omnidirectional aerials on the router.

Replace all the antennas!!!

small update:

the 1W alfa arrived today, and with the omnidirectional aerial its already boosted my signal significantly.

Generic Dual aerial thing:

Adams: 68% -> 92%
9446E6: 76% -> 88%



so in all seriousness, if you want good wifi... start with a good adaptor. THEN work on silly aerial tweaks.

Is this the one?

thats the one.


tried with a bunch of aerials, but i get no real gains using anything better than the provided 5db. its pretty well matched to the adaptor.


short version: good power, range. second best adaptor i've ever used (the white panel is better in almost every way). biggest problem, i'm only seeing about 400KB/s over a network with this adaptor, whereas the big white one manages about 1.2MB/s (54g network). its still a good step up from the dual aerial kinamax i tried earlier.

What make is the Chinese one with the squarial?

Just in case you want to check my math:

Also, here's some references on other good 2.4GHz home made antennas:

Helical:

Yagi:

Biconical or Bowtie:
http://www.rcgroups.com/forums/showthread.php?t=1328260

All of those can be made from everyday supplies, the Bowtie is the easiest as it's tuning is almost nill to get it to operate at the center frequency. Plus it can have up to 11 dBi of Gain and will beat most patch antennas.

Oh, I'm not trying to be a smartass. When half of the forum shows up to help a member talk about a Power Supply or Case suggestion nobody's a smartass in that scenario. I enjoy Antenna design and have a great career with them, so what if I post about something I love.

I nearly started neg then. Deep breath.

Right there was a joke thing at the end of my comment dude it was a light hearted jibe wherein I asked you to show a pic, text can seam harsh but no insult was intended and you're input is useful and helpful chears for the links .

kinamax ts-9900


its specs are clearly faked/exaggerated, but its a solid adaptor in every aspect. Its only downside is no external aerial, you're stuck with the directional panel it comes with.

 

[Mussels]

i left the kinamax squarial scanning overnight...

 

[Mussels]

trying out a new (crappy) design today with more of the foil lids.


instead of doing them horizontal, i'm trying vertical - they'll be smaller, which shouldnt be a problem with an omni aerial. then i'll try two rows of them veritcal, and see if a larger or smaller area helps.


using the signal 'adams' for comparison (i've got clear line of sight and i know the people there).

This time around i went for 20+ 'samples' and used the average.


1W Alfa w/ 10db omni huge ass aerial: 74%

+ 2 horizontal lids: 77% (admittedly this one was assembled... poorly)

+ 3 vertical lids: 79%

+ 6 lids 68% XD i'm assuiming the fact it has no smooth curves and is instead lumpy pieces stapled together unevenly is a bad thing


what i learned: covering the height of the aerial helps, but it needs to be a smooth curve.

Would you mind posting pictures? By "covering the height" you mean going beyond the tip?

If your findings are any good, I may need to order me some takeaway...

 

[Steevo]

Look here noob.

Take the "cm" of the frequency you are looking to use and create a parabola with the "cm" as the "radius" of the parabola or "dish" to the antenna then place the "antenna" in the center or "focal point" of the parabola.


13cm for 2.4Ghz


Convert the satanic "cm" into a real measurement like inches, which are totally factual and real, not like the imaginary meter and associated units...... come out with 5.1 and we can then create this reflection "dish".


I am totally going to patent the idea. So making this now is a breach of my IP and I will vigorously protect my research here!!!!

i have no idea what you just said.

I don't know if this was aimed at you but (EDIT:Steevo's) comment was rude and incomplete. I thought that maybe FreedomEclipse or I was the target of (EDIT: Steevo's) comment.

In any event, I like this post. It's useful, shows what can be achieved (on a budget) and your documenting your data which helps everyone.

Have a nice day!

aimed at steevo. he was using numbers and stuff.

I meant Steevo. Not you.

I can do math too: (2+2=4) (aimed at Steevo)

Maybe Steevo was trying to be comical with the intellectual rights thing. But as presented, I don't see any patents forthcoming. Maybe if Steevo elaborated this idea with tables, pictures and diagrams we could see if his ideas are workable.

Guys, Steevo was not intentionally being rude, that post had sarcasm written all over it. That being said, sift through the crap and there's some good info there.

Mussels, why are all the pictures you posted upside-down?

If it were not for the opening line, which sets the tone, I would agree.

The problem is print media and not knowing a guy's brand of humor.

Steevo has always given solid advice so I hope he takes my comments in jest.

Satanic numbers, noooooooo -/----.

 

[Steevo]

Yes. The answers to all of life's questions is here.

Steevo and Mussels have jabbed each other back and forth for years, I've seen it before and I'm sure this won't be the last time. I suspect that's where the "noob" comes from. His second line is a bit incoherent, but is still informative. Then he has the line about "Convert the satanic "cm" into a real measurement like inches, which are totally factual and real, not like the imaginary meter and associated units" and that's where I lost it and realized he was trolling
At any rate, re-read his post, have a good chuckle, and let's get back on track.

Mussels, have you tried using the take-out lids for shielding only? As in placing the "metallic" side away from the antenna and covering the side the antenna is on with some aluminium foil? Shiny side toward the antenna, not the dull side. I don't know if that would make a difference, but it seems like the shiny side would "reflect" the signal better without "diffusing" it.

EDIT: Steevo trolled us again
A .gif that does NOTHING!

 

[Mussels]

i've played with it as shielding, and all it does is cuts out a signal from one direction.


its useful if you're in a congested area and want to reduce interference, or keep unwanted guests off your router.

Right, but you could still use it as a backing for a better material is where I was coming from.

well thats true. i could set them up in a nice 'dish' and then stickytape some al foil over it. i wont because that shit annoys me, but i could.

Seriously, a parabola with a 5.1" radius will provide the best results.
