The "SWLZ" Balun is designed to 'match' your Shortwave
Listener (SWL) Antenna (9:1 Ratio) with the very common
and easy to get RG-6 (RG6) 75 Ohm Coax Cable used in
Satellite TV and Cable TV Systems that is very low loss
and uses standard "F" connectors.

Hi RHF

Yes I have bought from him twice and he's good people and his products are
well made. Plus, he took lots of his personal time to explain things to me
about baluns way back when. I like him and people here shouldn't hesitate to
buy from him.

Lucky

Junkies like him and home garage inventors come up with some good things
sometimes.

Thanks for the information,RHF.I didn't think you are the Junkie.I have
a few ideas of my own,but I am not smart enough to design and develope
them.

This type of balun has been around for some time. Nothing new.

Hi RHF,
.
I am working with some prototypes on this
antenna match with "F" connector.
.
I think I will stay with the 9:1 version for this match
as the losses are a little more when trying to feed
the 10:1 into 75 ohm coax rather than 50 ohm.
.
You will have a little loss converting the 75 ohm coax
to 50 ohm adapters but that is so small that the gain
you receive on the balun conversion will be dominating factor.
.
I have updated my website with the balun information
and put a link to the radio shack "F" adapters.
.
I should have working units for sale by next week.
(SWLZ Model / $17.50 each + S&H)
.
Thanks again your your advice and tips.
.
Regards, Jason [KG7RO]
