    "content": "Hi, Tim;\n\nWe still make the S/L patch feeds and may bring back the tribander, if\nthere's enough demand.  We also still produce the 1.2m and 1.8m dish kits\nand now have a 2.4m kit in the works.  It's been the UAV industry that's\nkept us alive since the failure of AO-40, so our products are now made from\naircraft grade aluminum and are milspec Class II gold anodized.\n\n73,\n\nRick Fletcher, W7YP\nTekSharp\nP.O.

They certainly\ndo not make the tri-band feed, but I was able to get a dual band patch from\nthem in June 2009 for one of their hardware cloth dishes.\n\n\n73's,\nTim - N8DEU\n\n\n----- Original Message -----\nFrom: \"K5OE\" <[email protected]>\nTo: <[email protected]>\nSent: Wednesday, January 04, 2012 4:37 PM\nSubject: [amsat-bb] Re: Looking for a G3RUH dish\n\n\n>\n> Bob,\n> Regarding your Cu wire dish... you might look at the Tek Sharp dishes as \n> an easier alternative to \"rolling your own.\"  I picked one up on ebay \n> about a year ago and put it in my attic... waiting for amsat-dl :-)\n>\n> http://www.plumdragon.com/teksharp/hr_AO-40_products.htm\n>\n> Drew,\n> I have a spare PF dish about 60 cm, but it is steel, not aluminum like the\n\n> G3RUH.
