Re: Gun precision / dispersion

The 2x6 m antennas were common mode. Oh, wow! That would mean an increase from 10 tranmitting dipoles on 2x4m antenna to 32 transmitting dipoles. And an increase from 10 receiving dipoles to 32 receiving dipoles. This would mean an effective range increase of 33% and give the 2x6m antenna a range v...

Re: Gun precision / dispersion

Dave, Peilverfahren A/N is lobe switching / Radattlepeilung, i.e. lobe on receive only? And phase shift measurement did not require the Radattelpeilung anymore? Do I understand you correct or am I mixing things up? And Bismarck had FuMG 40 not 39? Was 2000Hz vs 500Hz the discriminator or something ...

Re: Gun precision / dispersion

I understand, that the earlier 2x4m antenna was not common mode. I understand that the 3x6m antenna was common mode and horizontaly polarized. I was wondering about the 2 x 6m antenna on Scharnhorst's aft mount and Scheer and Lützow, since the 2x6m antenna appeared at around the same time as the la...

Re: Gun precision / dispersion

Good to see you again, Mr Saxton, Dave, if I may. Do you know, if the 2x6m vertical polarized antenna of the FuMG 40 / FuMO 26 used common mode like the large 3x6m horizontal polarized antenna? How did the ship borne control radars make use of the electronical scan? Was the electronical scan only u...

Re: Gun precision / dispersion

The Berlin antenna was plastic "polyrods" or "fingers" spinning around on a horizontal plate, inside a radome.* The presentation was on a PPI.

I'm pretty sure "owls ears" refers to the FuMO26 module PB for vertical, but I could be wrong.

*Note: Mk8 also used polyrods.

What, y'all think Putin and Xi would not take strategic advantage of the West's pathological self enslavement to a superstition?

Re: What is Putin up to?

For European economies it has been convenient and cheap (but extremely dangerous) to become reliant on Russia for energy supplies. No wrangling at home with Green Parties or populace about oil and gas exploration and production or siting wind/solar farms or nuclear plants, just buy the final produc...

Re: What is Putin up to?

.....I think the world just wishes Putin was put back in his box, (either above or below ground) but I fear the only ones who could do would be his own people, his own military,..... topple Putin before he goes too far. Be careful what you wish for. Those who would replace him are likely far more d...

Re: sabotage or carelessness?

These targets are all strategic assets and legitimate targets during the course of a war. It is not coincidence that they were attacked. Normally, if the actor has the means, these would be subject to air attack by missles or smart bombs. However, things have changed in the last ten years with techn...

Re: What is Putin up to?

Gentlemen, Re the explosions which fractured the gas pipelines, do you think it was (A) an accident, possibly caused by some WW2 ordinance or seismic movement, (B) the Russians, (why)? or (C) as was suggested in one of the UK papers, the Americans? Next Question! As the Ukrainians have apparently r...

Re: What is Putin up to?

particularly when one side threatens (so it has been reported) to use nuclear weapons, Frankly, I don't think that even Putin would go that far or that his senior military staff in the chain of command would even comply with an order to do so. History says that desperate people and/or desperate ins...
