There is no combination TV antenna on the market that has been "cut" or tuned to the exact frequency TV channels are on, its just impossible to do due to the broad bandwidth!

Indeed, but an antenna can be designed and made (common industry term, "cut") to yield a higher gain at the frequencies where the television transmissions exist.
Up until very recently, manufacturers didnt bother designing their antennas to receive VHF frequencies as high as 226.5MHz - sure they will still have gain up there, but not by intention, and typically lower gain than the intended frequencies.

This is bullshit also! The longer elements on a TV antenna are for the VHF channels. The higher the frequency you want to receive, the smaller the elements get.

Correct, I am well aware of this.
However I was specifically referring to the extremely long (over ~70cm span) elements. These VHF ch 6-12 antennas dont have elements spanning more than 50cm.

I would recommend to you that you go and work in the RF communications field designing and installing antenna systems for at least 7 years before you continue to dribble crap facts.

CBF, instead i just spend time communicating and working with my antenna manufacturer and GME Kingray. These are the guys with the experience and knowledge, and it is upon their advice and expertise that I am developing the range of products for dedicated digital reception for all situations, not just the ideal ones.
I would be seriously concerned if the head design engineer of GME Kingray (a name you should undoubtedly know and probably would respect) was "dribbling crap facts" to me.

No matter how many jaycar catalogs or any other text books you read it will give you fuck all knowledge when it comes to RF.
And don't try and tell someone that they don't know anything about the job they have been doing most of their working life!

I'd swear this is like the 4th or 5th profession you've claimed to have had Razz
