Oboe and G-H

[PMN1]

Oboe was restricted in the number of aircraft that could use it simultaeously but with G-H up to 100 aircraft could be using the system simultaneously - what was the difference between the two systems that allowed this?

The ranges of both were height dependant yet despite successful trials against Emden in September/October 43 of 'repeater' aircraft that would have allowed Oboe marking as far afield as Berlin, Bomber Command continued to rely on H2S and eventually having Oboe ground stations in mainland Europe after D-Day.

Was there any reason for this, one possible one is that not long after October 43 Bomber Commands targets were much closer to the UK in preparation for D-Day and therefor in normal Oboe range but it doesn't really explain why it wasn't developed for use once Arthur Harris got his aircraft bombing the targets he wanted again.

How much did the equipment and marking system fit for Oboe and G-H weigh?

The range of these systems was dependent on the height of the carrying aircraft which for the bomber Mosquito was about 36,000ft depending on variant and where you get the information from.

There was a Nightfighter conversion of around 5 aircraft, the MkXV, that had a ceiling of around 45,000ft thanks to extended wingspan and Merlin 72/73, 61 or 77 engines and had AI and an armament of 4 x 0.303mg.

Could this have been done to the bomber version to increase the ceiling and if so what kind of range would that have given the system?
