Hello All:

I need help with the actual specs and dimensions for a number of antennas. I have tried some antenna design (variant of NEC) but for whatever reason, the software never finishes the calculations. I looked at a whole bunch of software, but they were all out of my price range.

1. Require specs and dimensions for a high gain (15db+) Yagi/Uda for Tx/Rx on 880 through 960 Mhz
Yagi/Uda for Tx/Rx on 2400

2. Require specs and dimensions for a Horn antenna for Tx on 880 through 960 Mhz. (Rectangular Section)
Horn Antenna for Tx on 2400 Mhz
Especially on placement of "radiator" from side and rear walls.

3. Require specs and dimensions for a Parabolic Grid antenna for Tx/Rx on 880 through 960 Mhz
Parabolic Grid antenna for Tx/Rx on 2400Mhz and 5800 Mhz

I know this is a tall order but all help would be most welcome.

Thanks

Chay.
