| Ok the aircraft factor would be nullified but the same restrictions that pertained to the U-boats would also pertain to the RN who used the type 79 and 279 radar
The Type 79 and Type 279 were similar, both using separate transmitting and receiving antennas mounted on their own masts but rotating in synchronization. The antennas were small, resulting in a wide beam, which was adequate for detecting aerial intruders at ranges of up to about 80 kilometers (50 miles), but not so good at targeting naval vessels. It was also not very good at picking up low-flying aircraft.
The need for more precise targeting led Royal Navy researchers to hastily develop a 1.5 meter / 200 MHz radar, the "Type 286", based on the technology Bowen had developed during his AI work. The initial "Type 286M" used a fixed antenna, meaning the ship had to change direction to point the radar beam. The Type 286M could pick up a surfaced submarine at a distance of no more than a kilometer if the vessel carrying the radar was pointed in the right direction.
In March 1941, a Royal Navy destroyer managed to spot a German submarine at night using the Type 286M and then rammed the submarine, sending it to the bottom. However, that was basically nothing more than a stroke of luck. A "Type 286P" with a steerable antenna would be introduced in mid-1941.
U boats could probably transit the whole channel submerged without fear of recharging
