I have no experience of this at 136, but I remember visiting Ernie G3ERN at his QTH in Harlow and finding that I could walk all around the back yard and light a fluorescent tube when he keyed his top band mobile transmitter. This had a horizontal loading coil the length of a Commer J2 van with a shortish vertical whip at the opposite end from the feed.

It must have radiated fairly well as some time about 1963 I had a contact with him on a summer afternoon. He was in the New Forest and I was on Sark.
