I have a friend (no, really I do
) who's fitting SSB
to his steel
yacht (a Bruce Roberts
53 design). He has a Glomex RA700 7m whip antenna
which he has mounted close to the mizzen shrouds. To ensure it is completely supported he has tied it to the shrouds at regular intervals and even tied the tip to the mizzen spreaders. The antenna
thus lies completely alongside the shroud
I have suggested that this close proximity to the (grounded) shroud
may reduce the effective range of his SSB
. I have suggested he moves the antenna to the stern away from the masts and standing rigging
. He is concerned that the antenna may then be at risk if it is only supported only at it's base and at the top of his pushpit (about 1m up from the base). The instruction sheet says it should be supported 1.8m from the base but makes no other mention of additional supports.
What does the panel think? Is he making a grave error running the antenna so close to the shroud? And would the antenna be secure mounted at the stern with an additional support around 1m up from the base. I see this setup on many yachts. He's planning a 3-year voyage from the Med to Australia
Thanks for the advice!
