Question about using Hyperlink grid antenna

I am setting up a Hyperlink Tech "2.4 GHz 24 dBi High Performance Die Cast Reflector Grid" for Verizon EVDO reception. Although not quite PCS frequency, this antenna was recommended in another thread as performing well for PCS:

Question: in the above discussion, it is said:

"Be sure you mount them with the feed and ribbing running vertically."

The instructions included with the antenna describe two configurations: vertical parabola orientation with horizontal feed (for horz. polarization) or horizontal parabola with vertical feed (for vert. polarization). The image on their site shows the horiz. polarization configuration:

Can anyone clarify how I should configure the parabola and feed for PCS? Should I really orient the parabola vertically AND the feed vertically?

thanks!

CEL/PCS use vertical polarization. Your antenna should also use vertical polarization. I would followed the suggestion in the post by n6gn: "Be sure you mount them with the feed and ribbing running vertically." I would assemble the parabola exactly as on the illustration in your posting but turn it 90 degrees when mounting to achieve vertical polarization. That way the ribs are vertical and the feed is vertical.

Thanks. Ultimately, I did go with the vertical polarization orientation and it seems to be working.

How's it working for you? Were you using another type of antenna prior to this? If so, how do they compare?

Before using the grid, I was trying to use an omni. My location is very difficult due to hills and trees (I made another post detailing this).

The omni was not working very well, at least not consistently.

The grid antenna is fantastic. However, it took a lot of experimentation to find an optimal configuration. There are several towers in the vicinity and some were pulling better signal than others, no doubt due to topography, distance, and magic fairy dust.

Ultimately, I found an orientation that showed no signal at all with the omni (or the modem's internal antenna), but the grid is picking up a signal in the low to mid 90's.

That may not sound so great, but the "quality" of the signal must be quite good -- speed tests show about 1100kbps down, 300kbps up. I know that a friend with a much stronger signal strength (low 80's) is only getting a smidge more speed than this.

I'm pretty happy with the grid antenna considering the obstacles, and forestation, it is aiming through.

Is anyone making a grid antenna specifically tuned to the 1.9Ghz range? I'm also looking at this as an option.

I wonder how well this would work?

hey thebordellae is there one of those antennas that will work with sprint service ....they run on the 1900mhz side...also where did you get that ....I need one ....Im sure it would be greatly benificial to me as it was to you ....I am in an area like you explaned...hills and trees and such...
If yoiu could please let me know where i may find one for sprint u720
thanks

hey thank you so much for the quick reply on that ... I am thinking of buying one of these soon ..... I would love to see a download increase ... that would be awsome... thanks again ..

I forgot to add thebordella that I am running a wilson amp so I would only need to get the cable to reach from the antenna to the amp ..... I already have the cable and adapter that goes from the amp to my u720 modem.. Do you think that 3g would be able to get me the proper cable and adapter to get me up and running!?... I would be tickled to death to get a download like you said yours did... with the wilson trucker antenna I have seen around 400 to 500 kbs download and about 100 upload .... I am an avid ebayer so beter speed would mean less time spent buying and selling my things!! If I may ask around what did you spend to get the antenna and the cable that you needed to get up and running.. thanks for your reply...

Im using the same antenna in my setup. Actually I'm in the middle of my install right now. A thought occured to me while I was up on the roof setting the tripod mast. How will the antenna function after a hail/sleet/ice storm? Will a significant coating of Ice be detrimental to the signal?
