Message: [QUOTE="EscapeVelocity, post: 45507, member: 3771"]No I mean an 8 inch loop.  If you go to the FM antenna guide you will see a plethora of 8" loops.  You will also see small log periodics that are nowhere near 1/2 waves or 1/4 waves.  The FM Beambox is a classic example or 2 8" wires or a 1/4 wave dipole.  They may have matching networks, but you are thinking like a ham.  Sure its better to have a mathcing network if you are targeting a specific band or frequency, but Ive found that mismatch losses are very tolerable, not massive gain killers.  And for example as you well know, off resonance, dipoles increase in SWR and impedance.  You will always have mismatches on a broadband antenna at off resonant frequencies.  Im not saying its the perfect solution, but we are talking about broadbanding (or multimoding) here, on a secondary frequency spectrum and not the primary UHF television band.Correct, the elements are not tuned efficiently to the VHF band.  But they arent total duds either.  The proper sized reflector doubles the signal being fed into the UHF collinear broadside array.Yes it is an efficient re radiator of VHF High band energy.They also bring in energy from the direct transmission.Because if it is targeted to a specific frequency or band, then it will have a matching network, or you might wish to use larger tuned elements.  However if you are targeting a higher frequency band as well, as your primary band, then you match to that frequency spectrum, and take what you can get at the other (in this case VHF High).Not sure what you mean, but it is a coupling between the re-radiated signal from the parasitic element (the reflector) in addition to the primary transmission....and the UHF collinear broadside elements.True, but if you increase the classic 2 SWR and impedance limitations, that can be extended.It is well established that 3/4, 5/8, 1/2, 1/4, and 1/8 wave antenna elements have synergy with the full wave.--------------I think there is some mind blocks going on with regards to classic ham radio antenna truisms, plus also ANALOG television and there requirements.Hams like to pin down into the perfectly matched system to DX, and tweak their antennas and system to perfection. Analog television could not for example, handle any multipath, if you wanted the perfect picture.  However that isnt the case with digital.  I know FoxTV was discussing the necessity of signal quality, and because of the bandwagon discussion that followed, I decided not to join in and rock the boat.  But lets face it, as long as the digital tuner is staying locked on the primary or higher gain signal, then multipath does not affect the picture quality very much....not like on analog sets.The key is to be good enough to get the 1s and 0s coming through, and above the BER correction ability of the tuner.  Some margin above that is also beneficial (not only in the small increase in picture quality) but to ensure that you dont fall below the digital cliff with environmental changes affecting the transmitted signal.So while striving for the perfectly matched recieving system is laudable, one must realize that there is a lot of room away from that perfectly matched system, free from multipath, and so on and so forth, that will do the job, especially in the digital age.What say you?[/QUOTE]
