26 dBi ultra wide-band parabolic grid antenna

Post by xdavidx » Mon Jun 03, 2019 1:57 pm

Has anyone tried one of these?

On a related note, does anyone have any experience with any other high gain antennas that are wide-band (700 to 2700 MHz, minimum), yet have a narrow horizontal beam width?

I don't know of anyone that has.

Those two things don't coincide. If you want a higher gain antenna it is not typically going to be a wide bandwith. Especially when you get on the lower frequencies. A high gain 700mhz antenna is huge.

So do you think the claims of that 26 dBi antenna are far fetched?

Yes, and if they are true its most surely for the highest frequency that antenna supports, which is probably 2700mhz.

Claims are:

14-17 dBi
600-960 MHz

20-23 dBi
1700-2700 MHz

23-26 dBi
3000-6500 MHz

That doesn't seem too far off, but I'd go with something that supports MIMO, does that antenna support it? If I recall in the past that thing was only one polarization?

It says vertical or horizontal polarization.

You'd want both for LTE, not just one.

I was wondering about their use of "or" instead of "and". I am not exactly sure what they mean to say. I haven't been able to find any mention of mimo. However, given the price and size of the antenna, and challenge in mounting in a non-vertical way, it may be more of a rarity vs truly not supporting it. I'll contact the company. I believe they are also located in Texas.
