Hi Jim, The ferrite is made by RFS here in California and they use a different construction technique versus what you'd consider a regulator circulator/isolator design.
The seller "Rich" had three different frequency range panels for sale. The first batch were higher range 158 to 174 MHz, the mid range and the low ham range units most people here bought. I bought a lot/most of his higher range panels but I honestly haven't even had time to sweep all the models yet. The ferrite is not field tunable... I'm on a new super mega time sink project and I'll be mighty thin for the next couple of days. I do have some data sheets for the Alcatel Panels but it's more of the physical layout diagrams. The data for the ferrite is available in a table from the RFS Cellwave web site. back later... chow for now s. > "Jim Cicirello" <ka2...@...> wrote: > > For those of us who missed the boat or bid on the lower frequency > Alcatel Isolator Panels on E-Bay, I see the seller has more at a > higher operating frequency 148-164. > My question to Skipp and others who are familiar with these is: > For those of us who have Ham Transmitters in the 147 MHz 2-meter Band, > are these close enough to work?
