I have a reciever that has 2 screw antenna connections, 300 ohm. I
currently use RG-6 coax so I use a 4:1 matching tranformer at my
reciever and also at the Windom antenna in the attic.

I would like to setup a 90 ft random wire antenna outside using the
RG-6 and feed thru a ground block to the matching transformer into my
reciever. I'll need a 9:1 balun at the feed, but have not found a
ready made balun that accepts the "F" type coax connector. The ICE-180
and one currrently on eBay use a SO-239 connector and I have not found
connectors available to adapt to the RG-6.

Does any one know of a 9:1 Balun that accepts the "f" type connector?

300 ohms for an HF radio?

For many reasons I doubt that.

Common balanced impedances are 150, ~450 and I have seen a few 600 Ohm
RF devices.

300 would be extreme to the limits.

What type receiver is this?
