Hoping Tom or Ron will see this and chime in. Tom, I actually emailed you privately a few days back. Is there a reasonably priced roof mounted(magnetic) Omni on the market for 433/434? I know some of the falconry vendors sell them. But I wonder if there are cheaper options, cheaper than $90 plus shipping,out there. An internet search provides a number of return hits. But I am unsure of what I am buying and whether or not the seller is legit. Thanks in advance for the input.
