Hey kgb

Where'd you get the Iskra UHF-91X? I looked it up and the company is in Slovenia. You don't have any problems with overamplification of local signals with the 18db preamp? How do the 91X 'directors' stand up to birds and the elements? - I'd like to get some of the Seattle stations again.

Russian bandwidth range may differ from our North American bandwiths and that Iskra 91X antenna14db claim is for what frequency? So, don't get too excited based on such a loose claim to gain The 91XG and the MXU59 are designed for use in North America and North American frequencies.

It should work- the frequency band for the wideband Iskra UHF antennas is from 470MHz to 862MHz, although in Europe this translates to their channel 21 to 69 range. But 470MHz is our North American channel 14.

It's interesting to read through their catalogue, although I'm sure shipping and getting it battered around in transit might take some of the fun out of it.

For the home consumer within the reception ranges shown in the Antenna Chart there is no great win in spending the shipping and duty costs for a foreign antenna that is not marketed or available here. At the consumer level, any supposed* performance benefit over more common antennas is not so great as to merit such unusual efforts and cost.

* never trust gain figures that have not been corroborated by independent testing and/or modeling

Having said all that, it sure would be nice to have computer models of the Iskras. BTW I see that some of their antennas are not their own, so they use rebranding of other companies' antennas like many other vendors do.

Slovenia is former Yugoslavia… nothing to do with Russia.

Slovenia fully converted to DVB-T on December 1st, 2010

Slovenia uses MPEG-4 compression standard (AVC or H.264 for video and AAC for audio) for the digital terrestrial television platform.

I wish we had used this system here in North America too.

iskra

Hi there. I got antenna when we went on vacation in Europe 2 years ago. Is in box apr. 3" long, so I just check it in on aero port in Vienna. When we got to Vancouver BC box was in shreds , but luckily nothing was missing. Birds like to sit on it, but elements are sturdy. Well build. I contacted manufacturer to clear what gain they talking about, if is in dBd or dBi. So it is dBi and they don’t sell nothing in north America. Too bad, it is good antenna.

Ups

O,,,, sorry I forgot to mention,,,,,, YES overamplification is a problem, but I use two antennas. One for local channels and Iskra, so I just turn off Iskra and everything local locks in, on small antenna(13 element Yagi).

Thanks

That's good to know. The Iskra UHF-91X looked like a pretty good antenna from the information and pics I downloaded from the manufacturer's site. That's a similar thing I was going to do. Have one antenna with a preamp to try to get the Seattle stations and another unamplified one for the local ones, and have a A/B switch to go from one to the other. I could try combining them, but I'm not sure how that would work out.

switch

Hi. I thing switch would be better, you will have 3-4 dB loss on combiner, so for that reason I see switch as a only way to use all antenna gain.

Please keep this thread specifically about the Iskra antennas and use Archerotor's local reception thread to discuss his own situation.

I could try combining them, but I'm not sure how that would work out.

Youll lose gain from each antenna. Which, depending on the specific situation, could still be good enough.
