Dear Viacheslav,
Thanks for your reply.
My English is not so good and sorry for any misunderstandings.
I have added two kinds of coils to invoice and these coils were ready for shipment.
Because we could not find the information of female coils connector with 4 coax cables 30cm long with SMA.In order to avoid confusion,could you please send me a photo to verify.
We have 4-Channel Secondary Signal Amplifiers modified for 12V Power Supply.But I do not know how many you want.Please tell me at your convenience.
