Google Earth still shows my old N6BT DXU-32, which was one of two best antennas I have ever had as far as DXing, performance and convenience are concerned. Convenience is relative – that was one big antenna, and I am kind of surprised it did so well on top of a military mast – the AB-577. A testament to the engineering feats of military grade hardware. It actually scared me when I took it down – I realized how dangerous that was – if anything happened and the antenna crashed onto the roof. Yikes!
Anyway, this post is not about that – its the only place I can squeeze a 40M Bobtail Curtain – along the creek that defines the hypotenuse of my property line. It would end up being just fine for ZS and 3Y0B entities, and that means in the other direction, JA. It would have a deep null in the NE polar path and SW, so that kind of kills Glorioso – but I’ve been fixated on trying a full size 40M Bobtail for some time now.
I know even a dipole up 70′ would be better, but that isn’t going to happen. The 2 very large trees that used to be available (on my two neighbors properties and which I did secretly use without then ever knowing) have been cut down – they were “weed trees” – Monterrey Pines, which suck as far as trees go – they get tall and very dangerous as they get old. They were meant to be along the coast – not 20 miles inland where its too hot and dry for them.
Anyway, I’ll have to think about this a while. I sure wish I could talk to someone who has had experience with a 40M Bobtail. W8JI thinks Bruce Arrays and Bobtails and Half Squares aren’t all that great – but I have had very good experience with the Bruce Array – when I had a 4 element at my old Lafayette QTH, and here in Orinda, the DX Engineering DV-40P has been a solid performer.
If you have had experience with a Bobtail Curtain – let me know what you think.
