Local RSL is still using Band I. Not the smallest of aerials though.

On one Band 1 job, I used helical aerials to reduce the overall length and to make them less obvious. The radiation efficiency of a helical isn't as good as a conventional dipole, but that was easily overcome by using a bit more transmit power. The helical aerials I used were commercial ones designed for the old (illegal) high power 49MHz cordless phones. Their bandwidth was such that they would resonate reasonably well at 55MHz and I could even use them - after stretching them a bit - up at 60MHz. One well-known late 80s London station used that link for over a year before they "lost" the gear to the DTI
