JH1NPQ 小澤です。下記のHPにあるグリッドデッシュ(正確な呼び方不明)の利得ご存知の方いらしゃいますか。 http://www.markfossum.com/productindex.html This is the Andrew 18T-2400 Mag-Grid 2.4gig antenna. I have been selling these for use with the downconverters that I offer. If you would like to have one, just email me with your address and I'll send you a freight quote. (usually under $10 for shipping)
