That explains it. That explains the NJ call. Good to hear from you and thanks again for the pix.&nbsp; 73&nbsp; DH

&gt; 

&gt; &gt; That's ok, I sent thru the MGEF reflector. Did you used to be a 2?

&gt; &gt; &gt; 

&gt; &gt; &gt;By the way, I did not send the picture to the reflectors. 

&gt; &gt; &gt; 

&gt; &gt; &gt;It only went to you.

&gt; &gt; &gt; &gt; &gt;Who is MGEF ? 

&gt; &gt; &gt; &gt; &gt; 

&gt; &gt; &gt; &gt; &gt;That was from Field Day 1980 in Boonton, NJ.

&gt; &gt; &gt; &gt; &gt; 

&gt; &gt; &gt; &gt; &gt; &gt; Boy the guy in the picture looks familiar. He had a full head of 

&gt;hair! 

&gt; &gt; &gt; &gt; &gt;Also the station was in the white van and was the TR6, This probably 

&gt; &gt; &gt;dates 

&gt; &gt; &gt; &gt; &gt;to the late 70's or early 80's. Do you know.? MGEF could use this on 

&gt; &gt; &gt; &gt; &gt;their web site if you can date it. Thanks for the memory, 73, Don 

&gt;K1DH

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; Hi Jim, Why don't you contact Steve, K1FO directly?You can get 

&gt;his 

&gt; &gt; &gt; &gt; &gt;address 

&gt; &gt; &gt; &gt; &gt; &gt; &gt;from arrl.org and hopefully his phone number from 

&gt;switchboard.com. I 

&gt; &gt; &gt;know 

&gt; &gt; &gt; &gt; &gt;he 

&gt; &gt; &gt; &gt; &gt; &gt; &gt;has done extensive testing with his antennas and could steer you 

&gt;in 

&gt; &gt; &gt;the 

&gt; &gt; &gt; &gt; &gt; &gt; &gt;right direction. Good luck, 73 Don K1DH

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; 

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt;50mhz reflector 

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; 

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt;Hello all on the list and please forgive the bandwidth... 

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; 

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt;I'm trying to configure a couple of antenna arrays for 2M and 

&gt; &gt; &gt;432. 

&gt; &gt; &gt; &gt; &gt; &gt; &gt;Running 

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt;pairs of K1FO-12 for 2M and a pair of K1FO-15 for 432 in the 

&gt; &gt; &gt;E-plane 

&gt; &gt; &gt; &gt; &gt;on a 

&gt; &gt; &gt; &gt; &gt; &gt; &gt;48 

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt;ft tower, and while using Yagi Max I noticed that the wider 

&gt;the 

&gt; &gt; &gt;W/L 

&gt; &gt; &gt; &gt; &gt; &gt; &gt;spacing 

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt;between the antennas the narrower the beam width of the main 

&gt; &gt; &gt;lobe. 

&gt; &gt; &gt; &gt; &gt;Most 

&gt; &gt; &gt; &gt; &gt; &gt; &gt;of 

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt;the reading I've been seeing on the subject varies widely 

&gt; &gt; &gt;regarding 

&gt; &gt; &gt; &gt; &gt;the 

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt;'optimum' spacing. 

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt;The original design parameters by Paul, K1FO states one thing 

&gt;and 

&gt; &gt; &gt;YM 

&gt; &gt; &gt; &gt; &gt;3.11 

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt;states another for optimum spacing for antennas of his 

&gt;design. 

&gt; &gt; &gt;Also, 

&gt; &gt; &gt; &gt; &gt; &gt; &gt;others 

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt;have written that .9 W/L is optimal for all 

&gt;arrays...(confusion 

&gt; &gt; &gt;sets 

&gt; &gt; &gt; &gt; &gt;in.) 

&gt; &gt; &gt; &gt; &gt; &gt; &gt;I 

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt;have noticed a tighter pattern on the main lobe provides a 

&gt; &gt; &gt;cleaner 

&gt; &gt; &gt; &gt; &gt;F/B 

&gt; &gt; &gt; &gt; &gt; &gt; &gt;ratio 

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt;as well but it lends itself to having the antennas spaced at 

&gt;1.5 

&gt; &gt; &gt;W/L 

&gt; &gt; &gt; &gt; &gt;or 

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt;larger!!! 

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt;My question is rather simple...is it more desirable for one 

&gt;to 

&gt; &gt; &gt;have a 

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt;narrower or wider bandwidth pattern on the main lobe, or is 

&gt;it 

&gt; &gt; &gt;rather 

&gt; &gt; &gt; &gt; &gt;a 

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt;matter of aesthetics over gain? As the gain itself does not 

&gt; &gt; &gt;increase 

&gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt; &gt;appreciably to offset the necessity of a narrower band width 

&gt; &gt; &gt;pattern.
