LMR vs. RG-6 cable

[AK9R]

...I didn't even know they made a scanner antenna with a 75 ohm feed point.

I have long been of the opinion that cheap scanner antennas are made by the same people who make residential TV antennas. The construction practices are the same with un-welded seamed tubing and riveted connections.

I have to wonder why the designers did that, unless they wanted to be able to utilize cheap 300 to 75 ohm baluns.

Could be.

The late Bob Grove, who promoted the Scantenna, also promoted the use of RG6 cable. His reasoning was that it was cheap and readily available and that the impedance mis-match didn't matter. I always thought he was wrong, but that's water under the bridge now.

Hard to find a 1 1/2 to 1 Un Un, aka balan for coax cable.

I have a drawer full of 50 to 75ohm broad band RF transformers, they are not hard to find.
