Thank you for all your replies to my email below. I have already summerised your input (of course, with credit and copy right to you) and passed to local ham societies for their reference.
This is a great mail listing and I have been benefited from the learnt radio professions. Thanks a lot. 73 Johnny VR2XMC ________________________________ 寄件人︰ Johnny Siu <vr2...@yahoo.com.hk> 收件人︰ Elecraft <elecraft@mailman.qth.net> 傳送日期︰ 2014年04月4日 (週五) 11:05 AM 主題︰ OT: application of directional Quad in UHF Hello Elecrafters, It is off-topic and you can press 'DEL' now. Hong Kong is quite a hilly place in the rural areas. Local ham societies are often providing radio communication support services to charity organisations having fun raising sports activities in these areas. We have to set up UHF repeaters at the hill tops. Purely from the radio text books, a 3 element quad gives better performance than a 3 element yagi. However, I seldom see using directional Quad in the UHF repeaters. Apart from performance, are there any disdvantages (or advantages) of using directional quad instead of yagi in UHF repeaters? Could you share with me your experience in US? Thanks for your help in advance and please reply off-the-list to reduce the traffic in the mail listing (oh, yes, not forum!!) 73 Johnny VR2XMC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
