My experience with some products.


Aug 4, 2005
I just thought I would write a little something for the people on this forum struggling with Wi-Fi range issues. I solved mine after many problems using a couple of high-wattage items from

Here is my situation:
I live in a rural area serviced by Charter cable. I have the 10Mb down / 1Mb up service (which has been working great for me, btw). The problem came when my sister moved a couple of streets away from me. She just separated from her husband and they have yet to work out the alimony/child support issues, so she is kinda light on money right now. Unfortunately, her children "attend" the ONLINE middle / high school. Obviously she requires high-speed internet access, but would have a hard time affording the cost. So, being the loving brother that I am, I told her, "Hey, don't worry about it, I'll hook you up to my network and you can share my connection." She said, "Can you do that? I live too far away to string a cable across the neighborhood." I assured her I could do it using Wi-Fi. I then started making my own YAGI potato chip can antennas. I am an experienced A+-certified technician, so I figured it would be no big deal. Well, long story short, my antennas sucked. NO SIGNAL. I must have aimed and re-aimed the things for hours. I started to worry that I had bitten off more than I could chew. I did NOT want to tell my sister that I had failed. So I went looking on the web for some cheap antennas. Well, the first place I tried, "cheap" was the operative word. These things were terrible. Made out of the cheapest plastic possible. And then when they didn't work, I tried to get a refund but no one would help me. Those antennas are sitting in my closet, unused. Then I found I ordered two items:

This 500mW USB adapter + GRID 19dBi+ 5m/15ft for my sister's computer.

and this 2.4G GRID Antenna 24dBi + RSMA Pigtail for my Netgear router.

OK, now we're talking. After only one evening's setup time, including aiming / re-aiming, it is working like a charm. Not only does it work, but my sister has a consistent 60-75% signal strength. I ran the test at and she is getting the full 10mb download speed that I get from Charter.

I never did tell her I paid out of pocket for the non-working ones, she was just too happy to have working, fast internet.

So, obviously I recommend

Oh, and if you want to know where the crappy products came from, message me. I'll tell you who to avoid. I don't like to complain on forums unless I have to.

Thanks for listening, any questions? mail me,

Some pretty potent dBi units there...commonly only see 7 or 9 or maybe 11.

Any odd shaped tumors growing from yer head yet with all that power?

Bookmarked the site..thanks for the link.

Im thinking about buying one of those antennas will it work with my wrt54g in client mode so i can connect directly to the router and pull the internet from that?

that is good to hear about products but I am also looking at UBNT products to see if they work great also.

That's enough gain for a many-KM long-distance link. You should be getting better than 65-70% signal if everything is aimed properly and you have a clear LoS. Glad to hear the gear is working well for you though, I've bought some crummy antennas too (though I've also made a couple that work well ;)), and advise everyone to be wary, especially of omnidirectional antennas.

I can also recommend the Ubiquiti stuff. I've used this for a couple clients and can really recommend it, it's inexpensive, well built (for mounting outdoors), includes everything in one small box and the OS is really quite good.

Finally, 500mW at 19dBi violates the FCC rules. With your 19dBi antenna you should take that down to 350mW or so (25.5dBm) if you want to be compliant, not that anyone will ever bother you about it.

I have used on numerous wireless projects for clients. Glad you had a great experience with them
