Re: [IRCA] Beverage antenna kit



Thanks, Chuck for bringing the technical issues to the forefront.  I emailed the fellow directly, and here's his reply:

Dear canswl,

Good evening Gentleman ! 
I am using binocular ferrite cores for my 
transformers. The material I use closed to 43 
material . It has permeability of 850 .That 
permits me to bild matching trasformers to 
frequencys 1.7 to 27 MHz. My goal is - to let my 
customers experiment on a different bands ....
For MW I would use iron powder toroids with 
permeability of 10-40 ...I have such toroids but 
was using them only for 160 meters applications 
and stoped to do that ... 
Termination resistors I use are metal film 
resisotrs . After long experiments I use russian 2 
watt MLT-2 resistors . These resisotrs has 5 times 
overload ability and has very small reactive 
resistance in values range untill 500 OHm - due to 
their specific construction .. 
I have adjustable termination resistors as well .
We just moved to Canada and retuning to the 
business step-by-step . 4 BV antenna remote 
switches , bi-derectional BV , EMI coax arrestors 
, SDR receivers ,preamplfiers and other Low Band 
DX-ing gear will be available on eBay very soon 
...
You can try it . I sold my gear to almost 40 
countries ... It's just works .
Regards ! Alex

Looks like he's very accommodating for our needs.  Being so close, I might just have to pay him a visit sometime and see his line up!  ......Walt
