I was under the impression that a balun at the aerial itself also helped reduce noise pickup on the coax outer. In the USA, TV and FM aerials were usually supplied with a balun of the kind pictured. But from the various texts on the topic, one has the impression that in the UK it was common practice to connect coax (unbalanced) direct to nominally balanced aerials. Now that it's Proms season, absolutely the best possible reception of R3 would seem to be desirable. (And here in NZ we are lucky as RNZ Concert FM will run 66 Proms programmes this year.)
