Bob oh the ole dead bug is absolutely an option. Don't need LNA power so that makes everything even easier. I think there are numbers of grounds. But was hoping for a nice little PCB. Was going to buy several of the units but by the time on the same day I went to order magically they went up $5 each. I did submit a offer that was rejected. Oh well. Not that I needed 10 units. :-) Ones good enough. Regards Paul
