Irregular Geodesic domes[edit]

The radomes in the image here, are clearly based on a geodesic dome but have a more irregular distribution of the nodes. Can anyone confirm that the nodes are displaced randomly to avoid some sort of interference with the radar signal. -- Solipsist 08:17, 27 Mar 2005 (UTC)

A Guess?===[edit]

It looks to me that the distortion in the pattern of the structure is because it is not a perfect sphere. The bottom is open to allow for the hardware inside. If the materials of construction are transparent to electromagnetic waves, then it shouldn't matter.

Purpose[edit]

This sentence looks very clumsy to me: "Its shape is easily identified by its hardshell, which has strong properties against being damaged." Would anything be lost by the simpler: "It is easily identified by its strong shell."

or even:

"It is easily identified by its strong, damage-resistant, hardshell." - if 'hardshell' is a necessary piece of jargon. Dawright12 (talk) 11:00, 18 April 2011 (UTC)

Tinfoil Hat[edit]

I doubt anyone can confirm it, but are radomes sometimes used to disguise where the equipment within is being targeted? Captainmax 00:56, 15 August 2005 (UTC)

Before reading your question, I'd just added a note to this effect to the article! In the example of Menwith Hill, some dishes were uncovered at one point and observers could deduce which commercial satellites were being monitered. A PhD thesis on Menwith Hill also notes this useful propery of radomes. — Matt Crypto 21:52, 12 November 2005 (UTC)

Question[edit]

This may be stupid to ask but are the radar devices still able to perform their job while under the radomes? I think this should be in the article.

MAYBE an Answer[edit]

The Irraregular Gedesic Domes are to facilitate manufacturing of a two demensional shape and assembling it into a 3D shape with structural integrity. Example = a sphere is very strong, but to build a sphere of any size would be cost prohibitive and difficult at any large size, so you take small 2D shapes and sew them together and get a 3D soccer ball. As for the radomes use while covered, in some cases it is nessacary to remove the radome but if the antenna is designed correctly, taking into account the radome, they can remain covered and not interfere with RF transmission —The preceding unsigned comment was added by 204.203.50.2 (talk) 18:47, 16 February 2007 (UTC).

answer pt 2[edit]

radomes are made of material invisible to radar. It just blasts right through, the same way visible light passes through a clear pane of glass almost unimpeded. As an example, consider this: a car radio recieves radio transmissions much like a radar does, and a car radio will still pick up a clear signal in a typical garage attached to a suburban home even with all the doors and windows of the garage shut. The signal goes right through. —The preceding unsigned comment was added by 69.61.184.12 (talk) 14:55, 22 February 2007 (UTC).

I think transparency is such a common and familiar concept that it needs no elaboration here. Dawright12 (talk) 12:11, 18 April 2011 (UTC)

Answer pt 3[edit]

The material used is transparent to microwaves, and one of the driving forces behind the UK development of fibreglass/GRP was for producing radomes for the RAF's night fighter force, moulded plywood having been used previously.

Windloading[edit]

I have updated the article to note that radomes reduce wind loading. Not sure how to reference facts showing reduced windloading, here's one. See the datasheets here: http://www.pacwireless.com/products/soliddish_5ghz.shtml From a physics explanation, imaging a parachute right side up, and upside down. The upside down parachute is the shape of a radome and will go through the wind easier. The right side up chute is like a dish without a radome (or Mary Poppins umbrella) and will catch the wind much more effectively. --Jp498 (talk) 01:14, 1 March 2008 (UTC)
