Sectored antenna - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.


 Post subject: Sectored antenna
Posted: Mon May 09, 2005 9:42 am 
Hello,

My name is Manuel de la Puebla and I work for INDRA Systems (an Spanish technology employer). We are currently working on an ADS-B (Automatic Dependent Surveillance-Broadcast) project.

We are having a problem finding the antenna for this application. It should be a sectored antenna which covers the 360 degrees in azimut with sectors of 17 dBi of gain (around this value) each.

I am in charge of the antenna and I am having a hard time looking for a vendor we can buy this antenna from. It would impossible for us to design this antenna on our own, because we don´t have the necessary means (anechoic chamber and materials).

Does anybody know of any antenna vendor where we can buy this kind of antenna or maybe have it custom designed ?

I will appreciate any suggestion.

Thank you very much in advanced.

Chez gallego, porque no preguntas a www.fractus.com ?

Es una empresa espanola de Barca que esta espezialisado en antenas y si no tenen lo que necesitas por lo menos saben donde conseguir algo asi.
