New joint venture with @ea3hmj. We are working to set up a HP 8530A microwave receiver for antenna measurement
New joint venture with @ea3hmj. We are working to set up a HP 8530A microwave receiver for antenna measurement. The antenna under test is a 10GHz wg slot, rotated at hand to plot it. Now we need rotate the antenna automatically and maybe a anechoic chamber! LOL #ghz_bands
