Topband: #73 material for transformers

[Petr Ourednik]

Hi all,

I know that this topic has been discussed quite often over here and Tom,
W8JI
has also good article about that but I have simple question.
Which material is the best to use for rx antennas transformers please?

FairRite Products 2873000202
or
Amidon BN-73-202

Tom, W8Ji is talking about FairRite but other sources talking about
Amidon BN...

Thank You for info,

73 - Petr, OK1RP
