    Testing High Gain Antennas for Radar-Optical Axis

    @ VE1BLL : I confess, this was confused me too. @ IRstuff : Yes, this is a FINE idea and seems to be simple as well! I am not absolutely sure whether we can do this for all frequency ranges but you are absolutely right. The sun is a test signal Generator, it is for free and easy accessable -...

    Testing High Gain Antennas for Radar-Optical Axis

    @ IRstuff: 1. "focussed" means that all antenna beams point to the same target... 2. Yes, visibile light is different, but I think that we can't use this trick anyway. However, this idea is simple and interesting. If the focus of the light would aim on a target, the center of the antenna beam...

    Testing High Gain Antennas for Radar-Optical Axis

    Dear VE1BLL, no, we do not want to "transport" power to a distant point. We still want to transmit signals through independant dishes. It is just the propagation which causes the need of POWER. If all dishes would operate in the same frequency range from one BIG amplifier one could have...

    Testing High Gain Antennas for Radar-Optical Axis

    Dear VE1BLL, one dish is impossible, we need POWER for that distance. Therefore our antenna system has several dishes. But gated measurement is a great idea. I will check this. 73 de Andy

    Testing High Gain Antennas for Radar-Optical Axis

    Hi, I am looking to find some inspiration how to check a set of high gain parabolic dish microwave antennas. All these antennas are installed side by side on the same frame and this frame is turned into the direction towards the target by a massive turn table. I need to check whether these...
