As the above suggests, because the antenna is so tightly directional, the ERP can be very high. I don't know typical wattage sent to a radar dish but I did work with (non-pulsed) klystrons for many years. Off Topic: A BSEE guy once told me that he and another professional field engineer could never get the total power output ( including heat) in many klystrons to equal AC power input. Made me wonder... ________________________________ From: ChemE Stewart [mailto:[email protected]] Sent: Thursday, December 12, 2013 5:23 PM To: [email protected] Subject: Re: [Vo]:OT: 9th Grade Science Project: WiFi prevents seed germination Yes, those are NEXRAD 750,000 watt pulsed Dopplers there are another 50 or so TDWR 250,000 watt airport pulsed weather radars. Not shown. No long term studies have ever been done
