[Amps] Relay suggestions please

[Pete Smith N4ZR]

Sorry - same guy, different company.  TopTen was what I meant.  W2VJN 
was responsible for the design of their 6-way relay box.  The ones W2VJN 
used in the antenna switch are Schrack RTD 14012.  See 
<http://www.mouser.com/Search/ProductDetail.aspx?qs=CNrsY6Bml5lyPTnKwpMBZw%3D%3D>.  
$2.34 in onesie quantities.

I misstated a couple of specs - they rate their relay boxes for 1 KW 
RTTY to 30 MHz at swr of <1.5:1.  George told me he had tested to 3:1, 
so I suppose he was just being conservative.
