Hello))
I am interested in the question whether it is possible to connect two external antennas to the Wi-Fi card (adapter) or to the point, to the router, provided that the connector is one.
It means something like a splitter, double, tee ...
And will there be any sense from this ???



Rep: (1372)
Coordinate tired of these antennas ... on "just like that through a twin-tee" - it will probably only get worse ...

Hello.
2BBSR_CS, I will add cooler.nvkz, a reference to the theory Matching range antennas144 and 432 MHz. For the sake of interest, you can see, your range is much higher, then every mm of cable matters!
Successes.

Hello!
Please tell me, who know ... is it possible to replace the internal antenna of the router to external? There is no need for this? It is clear that sichto theoretically possible, because the router has an antenna in itself, ie, inside ... my them already six of which 3 operate in the range of 2.4. It is clear that there is a commercially available external antenna cables 2.4 range. But still ... the last time I "soldered-ludil" still in school ... That Hodel to hear the thoughts of experts. What and how ... does it make sense? Well, again, theoretically ... external antenna with 9 dB gain better internal ... but then thought ... but as you need? all three change immediately? Maybe some dop.infa need?



Rep: (4)
disassemble the router, inspect the board for razmchiku, although most often there is a non-soldering place, go in there and solder the antenna or wiring from the antenna, see if the mikruhi waffles go to this place, it happens that the smd jumper nadikut, you can buy a slot and cut into the case , I met such cheapness in TP-Link routers, a nest on the case anne on the board.
Look at such a plan manuals, I think will understand what's what:

Rep: (7)
The conclusion of the article about the test of routers - Linksys WRT610N was the winner in the current testing! I agree completely as the owner. I want to add external antennas to 2.4 for this particular device. Those. replace native to external. let's say an antenna from Tend. Of course, I would like to do the same with the 5GHz range antennas ... (although I only have one "receiver" working at 5 GHz and it lies quietly in the box).
At the same time, "gather dust" on the shelf D-link DIR-625 H \ w Ver.C1, F \ W Ver.3.00 (P / N BIR 625ANA ... C1). which has two antennas and both external and removable. But since there is no information about him in general, how is it dumb to put it into work ....

advokat-donetsk1111, I have a router D-Link DIR-300NRU B1, the work was satisfied only the first time, and then around to populate the heap of vayfay points and had to choose an empty channel, then looked audit iron, I just took it and alter the alternative firmware DD-WRT, and more settings improvements are not particularly noticed only setting shaft is now, by default there in DD-WRT power 71mvt transmitter, I declined to 61mvt and reception become more confident, then noticed that antenka in router staffing all 2dB, lay me antenka to 5dB, twisting and reception got even better, with the condition h the DD-WRT I reduced the power of the transmitter has been reduced, I think the power can be raised to 71mvt again or to experiment with self-made antenna in such a plan:

Good day.
I want to make myself a Wi-Fi in the yard, respectively, I need a Wi-Fi antenna:

1). The shape and size of the yard: rectangular, about 20m by 60m, it is desirable to catch in the far corner, in the yard there are quite a lot of trees with a thick crown of leaves, the height of the trees is about 10 to 20.23 m
2). Antenna installation height: about 10-12m (3rd floor)
3). Router: Zyxel Keentic
4). Antenna type: external / street, omnidirectional?
5). Distance from the router to the antenna (cable length): 5-6m
6). Internet for smartphone and tablet: surf on the Internet.
7). Budget: up to 4000 rubles inclusive

What do you advise?

Now a lot of free points wi fi - cafes, commercial banks, and even online operators distribute in test mode. but the signal itself is very sensitive to interference and rasstoyaniyu.skazhu immediately - if the point of access is visible, but difficult to connect because of an unstable signal - bound due to distances of 200 meters or some sort of construction nepozvolyaet is opposite retronslyatora (corner of a house or a tree) y I personally, and the first and second meter cable prisutstvuet.10 significant loss of signal is not given.

I had to make a square hole in the plastic frame. It is difficult to cut it out - a hot knife and glass of the wheel, and you need to make a neatly small square hole of about 5 * 5 mm.

It looks like that inside, it was glued with glue for the moment. The glue was applied 3 times with an interval of 12 hours - it turned out to be both firm and elastic.
Attached Image

at the end, while the glue is still elastic, but no longer sticks to the fingers - you can make a groove for landing the back cover (I have a latch nearby)
then I had to file a back cover.

it looks like the finished outside

and so

This is an adapter with an rg174 cable, then through centimeters 20, a "N type" connector is connected to the cable, which connects to the "N type" connector under the rg 58 cable.
rg58 I have 10 meters with a “canned antenna” (for rg58 the losses are minimal, I personally didn’t notice differences in signal level between 1m and 10m cable. I checked the program with a wi fi analyzer)

now I even connect to a home BB via a USB tablet and with the help of the PdaNet program I get free access.

Oh, cool. Perhaps still links under kat you will take out on sellers of sockets?



Rep: (54)
I can’t throw links - since this will be regarded as a hidden advertising of online stores. A cruel rule on the part of the site - since I had to google for almost three days to find something at affordable prices. Pro correspondence with sellers on the subject "is it in stock, and so on "already silent.
But I will try to prompt "without advertising".
since I am a resident of Ukraine, I bought everything right there. The first photograph of the MCX connector from one very popular Ukrainian auction.
almost all other connectors were bought in the online store (hereinafter the incomplete name for easy search in google) "Mobil ..."
and the most difficult and expensive for the price is the N-type female connector (socket) for cable rg 174. even according to the labeling it goes like for the RG-316 / U cable. the shop works only by bank transfer and in the name there are letters Sel ...
It is easier for residents of the capital - they have a radio market. In our city, the problem can be explained even to sellers of radio shops - what do you want from them.
add tablet photos
N on the right is German, on the left is N (male) in rg 58.

It looks like the disconnected adapter from the tablet. "German is suspended" on the cord (clings to the tablet case) so as not to tear the cable
Attached Image

This design is complete and can be seen on the scale of the signal level.

so it looks like "for transportation" (a rubber band is sewn on the case - so that the "German" does not hang out)

And this is cut in the case for the MCX connector

This is a link to the MCX connector for rg58 (crimp), it is inserted into the tablet. For the seller for an additional symbolic fee, you can agree to crimp the connector on the meter cable rg174

on the other side of the cable "German" (dear however. a little more than $ 10). the shop only works by bank transfer, but you can try to negotiate by replenishing the card of the private bank

I'd like to add that for the second month I use the Internet at home and at work for free, for free or "for free" (as you like) :)
I can also share the experience of setting up and manufacturing a "canned antenna" - costs "0" kopecks (except for an electrician for a soldering iron)
the lack of MCX connectors is approximately the specified cycle of 500 connections and disconnections. since I have to switch 2 times a day (home work) I use "N" connectors. tested on personal experience, while looking for a "German").
