I haven't seen Firdell Blipper being mentioned here yet
It may not be cheap, but you can get a stainless bracket for it which holds it in place too. Unfortunately, the stainless screws that hold the bracket onto its base lost their thread in some rough weather, so I had it welded to its base and now the thing is solid as a rock.
I personally wouldn't get an aerial the same height as the reflector and put it right next to it since it will have some effect on the transmission/reception (I'm sure this was discussed sometime back). Fine, probably if it was in the haven, then no one will notice, but for example, if I'm 20miles offshore at the Smalls, I'd want to ensure that the aerials are much higher to get all round reception without anything in their way.
