GW4RWR
Antennas used:
Apart from dipoles between chimneys for 40m, 20m and 17m, I've only used yagis.
HF - 2 el Western DX32, from GW3RUE, (a swap for Swinburne DR600) .
28MHz -
50MHz - 3 el yagi on former Jaybeam boom.
70MHz –
5 el MET yagi (3.4m boom) from G3WOS, 2004. Light, flexible elements.
144MHz – a variety over the years, in this order:
8el Jaybeam (won Single Op Portable of Sept 1982 contest, aged 16, from Moel y Parc)
6 el Quad Jaybeam (GW4HBZ antenna, heavy, I preferred the 8el Jaybeam)
4x16 el Jaybeam
4x17el Tonna (nicer pattern) 
2 x 9 el portable Tonna. Lighter, more gain and wider pattern than a single 17el
432MHz - 19 el Tonna (very clean)
1296MHz - 23 el Tonna. Sold at Weston Aerodrome, along with the SSB Electronic
kit modules and Mitsubishi brick amp. I wasn't able to make much use of all
this, my home being in a deep valley. Although twenty years later I regret having sold it. I first used the transverter on 28MHz, and once I'd retuned the LO
from 1268 to 1152MHz the sensitivity was noticeably much better.
