[QUOTE="ProjectSHO89, post: 122588, member: 4698"]Both Nist's charts and AD's tech data sheets are the results of software simulations. AD lists, in the notes, that the balun is not included. It would be accurate to say that UHF PCB baluns do not do well at VHF frequencies and that VHF PCB baluns do not well at UHF frequencies. There are VHF PCB baluns that do quite well for their design frequencies. There is zero evidence or indication that would suggest such. The specifications are similar to the M4 which as similar dimensions.[/QUOTE]
