Nice unboxing! I wanted this antenna in the mid 2000s but never had one.
@@oz_dx thanks!
All MW DX will be your!))
It is quite impressive peace of kit available commercialy. There's various connection methods to experiment with and even passive loop can be incorporated as I found with my experiments to get even more gain. Bob Crane (owner of the company) in one of the articles also mentioned about it. He used twin coil ferrite antenna with Select-A-Tenna passive MW loop.
The only thing which is a little bit annoying - PS/2 - DIN6 connectors. But if you keep in mind that this antenna first came around 2000s it is normal at the time.
@@HardcoreDXLithuania Interesting to see your results! Best DX!
@@AlexeyDXman thanks! Now only the time is my main problem. :)
Did you try it with the CCradio-EP Pro? I'm qurious how much it helps to big, well performing radio. My AN200 barly make any difference to XHDATA D-808 or my CCradio-EP. Of course, I use inductive coupling.
Thank you for your question. The fact is that the better the radio is on MW - less noticeable effect. I tried quickly with my CC Radio EP Pro with inductive coupling method and what I noticed as both: antenna and radio has fine tuning of their inside ferrite - sometimes they null each other and the opposite effect is achieved. So you need to play with it and find the right way to use both at the same time. I haven't tried yet with bare wire direct connection. Thought it will not disconnect internal ferrite like on original CC Radio EP.
@@HardcoreDXLithuania Yes, I'm aware that the inductive coupling is not working well on good MW sets ( but what a difference make with weaker radios), but I have no idea how it could be with active antennas with direct connection. I don't think that I could buy the Twin coil ferrite, but I'm considering the Tecsun AN- 48x, especially now, when I have CCRdaio-EP with MW antenna inputs.
@@HristosTrUK and CC Radio EP disconnect internal ferrite when switched to external.
I think they dont sale outside USA
Originally designed in USA by Chris Justice. Made by Sangean. Orientated to US market as all C. Crane products. But still can be found used or even mint condition on eBay.com auctions.
Пока не пойму: активная антенна что ли, выносная, на ферритовом сердечнике?
Inside antenna unit there's 20 cm long ferrite bar with double coil method connected to PCB. It is controled with control unit (little box) for main tuning (big wheel) and later with fine tuning (little wheel in the middle). Best method I found so far is connecting it to radio by induction method, with that little ferrite stick from the control unit. You place it somewhere near radios inside ferrite "sweet spot".
