I need a photo reference for US Navy SJ and SD radar antennae. I’ve tried googling the web and find all kinds of good technical references but no photos. Any help would be very much appreciated.
Well, just to answer my own request, I finally found a ton of them at NavSource Online.
i know why you could not find them at first
they were wrapped up in that stuff called
government red tape [:-,] lol lol[(-D]
Yeah!, and until you get it ALL off, you should see the VSWR you get!![oops]
You don’t want to unwrap too much of that red tape cause that will allow water into the wave guide and that VSWR will be out of control…

Actually, and this is no joke, red tape IS what we use for holding stuff together in nuclear reactor repair. The duct tape we use is red which differentiates it from generic duct tape. The generic duct tape contains chlorides which, when it comes in contact with piping, can cause corrosion. Red tape is chloride free and costs eight times as much as regular tape. We go thruogh cases of the stuff every year. Tie wraps, or stay straps, are another favorite repair item. Feel safe now??
Not really.
You use duct tape?
In neclear reactor repair?[%-)]
Really. But to elaborate just a little; we don’t actually repair components with the tape, but use it in conjunction with the repairs such as temporary containments, sealing bags and etc.
Is that the stuff with the white line along the centre to guide you when you wrap it round something? If so it’s the same stuff we have started to sell where I work. Great tape but very expensive. Very good for the offshore industry as well as our nuke builder in townl. Handy in that you can cut it off and it leaves no residue.
I don’t think it is what you are referring to, there is no white line and it will leave a residue if it gets thermally hot and left in place to long. But it is good stuff in normal use. The residue is fairly easy to remove.
