Are you talking to ET ?
If he is on the moon I could! I bounce signals off the moon on some ham radio bands, other antennas are for long range(beyond line of sight) VHF/UHF/Microwave contacts... last summer I made a 600 mile contact on 1.296ghz (half the frequency your microwave oven operates at)... way beyond line of sight! On 144mhz I have talked to New Zealand, South Africa, Australia, All over Europe, Russia...
Adding the ability to do that on 1.296ghz(2.1 meter dish antenna like they used for TV back in the day) and 432mhz(Four 25 foot long yagi array that has a rotator to point them up like this pic of my 144mhz antennas tracking the moon)
