Need Antenna Advice
 

I need some advice on a CLP5130-1 Log Peiodic made by Create.
I have had one of these mounted vertical on a fiberglass mast for 10
years now and it survived many windstorms until last week. It would
have survived that one also if my 68ft selfsupport tower did not land
on it :)

Anyways, what I intend to do is to repurchase a new one to mount
vertical, and also another one to mount just below it horizontal for
Television/FM reception. The one I use for scanning I feed with 5/8
hardline and I was intending on putting some Times microwave 75ohm
hardline (1/2 inch) LMR 600-75 on the second one used for
television,reduce it down to an F connector and put in a regular
VHF/UHF preamp that adapts out to the "N' connector of the Create.

My question is, has anyone used these as a television antenna. I know
they claim 10-12db gain across the whole band which is what my TV
antenna boasted as well. I have seen posts that they do not really
have as much gain as Create says, but then, does my Delhi Deep Fringe
tv antenna which I have to replace also have the stated 7db gain on
VHF lo and 13db gain on VHF-HI/UHF.

Looking at the specs, you would say, they should perform the same. I
guess I am looking for some advice as to real world experiences since
you cannot believe what is printed.
Do these work good as a tv antenna? You may say this is a bit extreme
in cost. The wind loading on these antennas is stated around 1 square
ft . Their relitively small "wind footprint" is attractive to me as I
am looking for lighter alternative with both being at the top of a new
68ft tower I want to stay up.

Thanks,

Hi Rob,

Typical specifications, yes.

have as much gain as Create says, but then, does my Delhi Deep Fringe
tv antenna which I have to replace also have the stated 7db gain on
VHF lo and 13db gain on VHF-HI/UHF.

All of this is also specs-manship. For the TV antenna, this gain can
be found for some regions and not others; and they can still claim the
better figures. The TV UHF band is immense, but in reality very
little of it is actually populated. The FCC of the late 40's must
have thought 88 channels would be needed eventually. They were wrong,
several hundred channels selling hoop earrings 24 hours a day would
have been an appalling prospect back then, and Newton Minnow would
have foamed at the mouth sputtering "vast wasteland."

You might find another vendor that offers a smaller antenna that
covers LESS spectrum with as much or more gain for all of your
pursuits. LPDAs are quite easy to predict (although the doing is a
bear) and as they are flat responsive (this is a trade-off for lower
gain with having so many elements) they represent a good general
coverage average gain solution.
