Higher frequencies allow better spacial resolution for radar, and smaller antennae for all devices (look how small the 880 MHz antennae on a cell phone is!). It also makes it harder to jam and detect. The early navigation devices would operate in the kiloHertz (KHz) range (like AM radio) while the radars would operate in the megaHertz (MHz) range (like FM radio). Modern radars operate in the GigaHertz (GHz) frequencies (like your 2.5 GHz cordless phone) and the cutting edge of radio technology is now moving into the TeraHertz range (you have probably never seen/used this unless you work in a lab like me). The far infrared frequencies are around 100 THz by comparison (near infrared is used for night vison).
In the biz, Radio Frequency technologies are referred to lovingly as "RF" (Arrrr, F like a Pirate would say it)...

KGP did put a disclaimer in the bottom of his original post stating that no specs were included in his source material.

# Also my source gave no info on the use and stats of any of the RADAR that was in use before Knickenbein, thats why it wasnt included in the list. Im not trying to exclude it. The point of my list is to point out the arms race the derived from the "original" use of the British RADAR and to point out the amazing accomplishments made along the way on "all" sides, not to denegrate anyones original efforts.

But to give you some idea of the RF's used, the original Wurzburg radar used 7-11kW / 3,750Hz with a Max range of 29km, whilst the later Jagdschloss
radar worked on 80kW /120-158MHz with a Max range of 150km and later refinements increased its range from 150km to 300km.
