What About This Antenna Is Superior Enough To Justify Cost?
I don't see any specs that are that impressive-like 8.2 dB over isotropic, not even over a tuned dipole.

Is THAT where they got the idea for the 486-SX?

Wouldn't be worth it to me because I rarely watch TV. But it is a pretty impressive antenna.
For anyone who does watch TV it would probably pay for itself pretty quickly if they switched fro cable or satellite.

I don't mean to brag, but I just put a puzzle together in 1 day and the box said 2-4 years.
Re: What About This Antenna Is Superior Enough To Justify Cast?
There's no way I could justify that kind of cost for a residential installation. Commercial, no problem. but that would be more due to the expected longevity, not necessarily the gain or other signal quality parameters.
Re: What About This Antenna Is Superior Enough To Justify Cast?
What sort of commercial application would there be for that antenna?

Maybe use at a cable TV company head end, far from the city. Or on a hi-rise luxury condo building roof, for a building wide CATV system !
It must have solid elements (not aluminum tubing), maybe silver plated connectors, and stainless steel hardware holding it together.
Must be Built to go on a tall tower where the wind and Ice is terrible, and surviving all !
Not for suburban homes , by any means !

Barely over 6.0 dBd. Not bad at Channel 2. Not very good on 7-13. Blonder Tongue mainly makes CATV and MATV equipment. I think they made more consumer oriented equipment 50 years ago, which was cheaper and in Allied Catalogs,

Blonder Tongue had a UHF only antenna, and some preamps in the 1970 Allied Catalog. Very reasonably priced.

Re: What About This Antenna Is Superior Enough To Justify Cost?
This is a classic wide band log periodic, so the gain is essentially the same over a large range of frequencies. There don't appear to be design gaps in frequency coverage. Just 54-216. The FCC Field Office in Farmington Hills used to have a HUQE log peoridic like that that probably went down to 15 or 20 MHz and at least as far up as 216 MHz. It is like a three element beam at each frequency, so something in the range of 6-7 dBd across the range. AT&T used to have ones that went down to at least 7 MHz for transoceanic long distance.

Re: What About This Antenna Is Superior Enough To Justify Cost?
I'm not sure I could bring myself to by a $800 for TV.
Re: What About This Antenna Is Superior Enough To Justify Cost?
If I was a TV guy I could. But since I rarely watch TV it would be a waste.
Now if it was for Radio - - -

Re: What About This Antenna Is Superior Enough To Justify Cost?
AT&T had (don't know if it's still there) for domestic use, a H*** 6.4 MHz to 30 MHz Log Periodic on an 85' tower at the Warren Main Central office in Sterling Hts. This was (is?) the company's Emergency Operations Center. The tower, antenna and commercial HF radio gear were part of the SHARES/NSEP radio service, a "Doomsday" radio system. When all else fails, the HF radio will work. This site was a secondary site on that system, the primary being near Chicago.
Re: What About This Antenna Is Superior Enough To Justify Cost?
I remember seeing the LP at Farmington hills and also In Warren, there were a few other HF LP antennas I have seen in my travels around MI before I retired ! CK722 has a good understanding on how they work, it's A lot different idea than a Yagi Design !
Aside; My first transistor audio amp homebrewed , used A Raytheon CK722 transistor ! Built it when I was about 15 years old and was amazed it worked on a couple D-cells and without a 350 V B+ supply
