Topband: Commercially available traps for BC Trapper?/ Topband trap dipole. Unadilla. /BCS

[Samir Popaja]

I ordered by mistake UNADILLA KW40 USA instead of KW40 EURO traps with KW80
CW for my BCS which was building on SPIDERBEAM 18m pole... I'm wondering if
it make bad impact on antenna, Battle Creek Special (160-80-40m)...

Thanks

One might try the Reyco Traps by Unadilla.  The problem is they come in 
pairs!  I guess one gets spare traps that way!
The web-site is:
http://www.unadilla.com/traps.htm

They are available at Amateur Electronic Supply, maybe Ham Radio Outlet and 
other stores.

I have no interest in these companys and I can only say that their WARC 
traps have worked fine for me in the past.

'allo ,


Is anyone using the Unadilla 80m traps to make a 160m
antenna.

If yes, which one do you have ? 
There are 2 types; one for american 80m ssb band and one for the american
80m 
cw band.  

I was wondering what sort of bandwidth these traps have.  We we do not have
the 
same frequencies as you in Europe.

I'm thinking of putting one in my inverted L. 

Thanks
