The lowest noise figure 1. I could see a problem like that developing if someone working in the field kludged together his own, two stage amplifier, but I can’t for the life of me figure how a manufactured product could develop more noise when operating in a lower gain mode. Looks like gobbledegook to me. Hi, I think I will hold off on my current setup since it is working good enough. The damage that amplifiers develop and impress upon that weakest channel are the accumulations of various degradation effects, and your best bet to save it, if you don’t have the means to sequestrate it that I do, is to be able to manually tweak the amplifier’s gain up and down, which you can’t do with this amplifier.
So could be very good feature when dealing with a mix of strong and weak signals, if it truly works.

As I understand it, when we measure the “strength” of a single, 8VSB channel, we are measuring the power developed across its width of about 5. Remove Advertisements Sponsored Links. Their drawing depicts the gain on six equal strength channels, with the individual output channel strengths not shown.
Unfortunately there are few trleves available to do this, and they require equipment to tune properly. The single, most important thing for anyone to do when using a broadband amplifier that televws being fed signals with widely differing signal levels is to attenuate the strongest before preamplifying.

Not sure if the versions from Solid Signal are US models. What are all of those other F-connectors for? AVS Forum articles Contests.

You can just come in here every day and do whatever you want and I’ll give you your B”. I haven’t had cause to analyze the architecture of preamplifiers with manual signal level controls lately.

When trying to salvage or sustain a weak signal in the presence of a stronger one there is no ideal, cumulative wattage level. Televes is a well known Spanish TV Antenna Manufacturer who has been in business for a very long time And nice to see Solid Ccatalogo now carrying Televes products and decent prices.
I believe the Kitztech KT is such an amplifier. I’m sure that this preamp could amplify one single channel to 52dBmV, but what if there are ten such channels, with, say, input levels of 45dBmV? I performed measurements on it at different gain settings and wasn’t impressed. This new version apparently is more designed for current spectrum, and has built in preamp with LTE filter. I’m sure I would hope that these values have been adjusted for the wider, European channel bandwidth.
Are there any current models of preamplifier that have manual gain adjustments that are not just input attenuators?
Stacking antennas is a better option where the spacing distance is set so that apertures don’t overlap. Would be interesting to hear reception reports, especially in regard to the smart Boss-Tech amplifier.

Caatlogo dBuV any greater than what Wineguard claims as the safe level for its amplifiers with a one channel load? This amplifier design doesn’t let the user think, or to utilize the fruits of his thinking. Solid signal is promoting them, saw them for sale there today.
Once, when I was not moving enough to show signs of life, she said, ” AntAltMikewhat are you doing? When you are trying to sustain the viability of signals coming off the same antenna that may have 40dB of signal level variance, it is not enough to have the amplifier adjust itself to a cumulative wattage level that limits some calculated intermodulation derivative to some arbitrary level.
BB code is On. Last edited by AntAltMike; at Is there some way to blow up the label to read it? And in many cases, televs don’t want to attenuate the entire spectrum, either, because in extreme cases, that will reduce the weak input signal unacceptably close to the noise floor.
Antennas pointed in different dw If you weaken the input into it, it would have to further amplify everything, noise and all, right up to it’s maximum gain.
If I thought these were better than 91XGs I’d have them. She said, “You’re not supposed to think. I consider that to be an unacceptably low number. When there’s overlap you don’t get any gain because the same signal appears on each section. Hopefully the same reasonable price.
