Would be interesting to hear reception reports, especially in regard to the smart Boss-Tech amplifier. When you are trying to sustain the telleves 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.


The latter two appear to be the 0211 and look very similar to the DAT HD, which was reviewed along with many other Antennas by the fol. If I thought these were better than 91XGs I’d have them. Ce signal is promoting them, saw them for sale there today. It looks like the table is showing that with such an input load, the maximum output level or each channel would be 17 to 18dB below that.

Their drawing depicts the gain on six equal strength channels, with the individual output channel strengths not shown. So could be very good feature when dealing with catakogo mix of strong and weak signals, if it truly works.

When there’s overlap you don’t get any gain because the same signal appears on each section. I’m sure that this heleves could amplify one single channel to 52dBmV, but what if there are ten such channels, with, say, input levels of 45dBmV? This new version apparently is more designed for current spectrum, and has built in preamp with LTE filter. 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.

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. This amplifier is a seriously bad idea. Originally Posted by Calaveras. If so I would prefer those to this one.

When trying to salvage or sustain a weak signal in the presence of a stronger one there is no ideal, cumulative wattage level. Tech support for Antennas Direct. Originally Posted by tylerSC. The noise figure begins to degrade below a gain of 30 dB, 3dB at 20 dB of gain and is between dB at 15 dB gain.

I remember that with most 30dB power amplifiers, the so called “level” or “gain” adjustment was just a variable attenuator on the signal input path, whereas the higher gain power amplifiers actually had two stages of amplification, with the attenuator in between the stages. You want to save the weakest signal, come Hell or high water.

Not sure if the versions from Solid Signal are US models. So could help in problem areas, but the 91XG and a Juice preamp may be suitable and more affordable, as the Televes is more expensive and not widely distributed in the US.

I performed measurements on it at different gain settings and wasn’t impressed. I consider that to be an unacceptably low number. Remove Advertisements Sponsored Links. The single, most important thing for anyone to do when using a broadband amplifier that is being fed signals with widely differing signal levels is to attenuate the strongest before preamplifying.

You can just come in here every day and do whatever you want and I’ll give you your B”. I’d like to chime in to point out that the new Televes US models filter frequencies above MHz and ship with a UL listed power supply unit.

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. I used to have a math teacher who was really committed to “rote”. The KT is a two-stage amp with a variable attenuator between televez stages. I think they were a bit surprised they sold out so quickly. In less than a week, most teeves these Televes antennas from Solid Signal have sold out.


Looks tepeves gobbledegook to me. Is there some way to blow up the label to read it? They have ordered a new shipment of the larger DAT versions which should be available again in a few weeks. Is dBuV any greater than what Wineguard claims as the safe level for its amplifiers with a tteleves channel load? Which also has built in Boss-Tech amplifier but a more discreet form factor. The lowest noise figure 1. I do the thinking here.

FWIW, I know that as recently as a few years ago, a lot of Telwves amplifiers still used analog signal levels in their ratings, which grossly inflated them. Supposedly the built in Boss-Tech preamp has automatic adjustable gain to prevent overload and adjust accordingly to the signal strength needed to receive a specific RF signal. Here is one way it might be possible. Once, when I was not moving enough to show signs of life, she said, televess AntAltMikewhat are you doing?

This amplifier design doesn’t let the user think, or to utilize the fruits of his thinking.

Televes reportedly makes good antennas and is known for the triple boom yagi. I can barely conceptualize how that could even be physically possible if the gain adjustment configuration is interstage attenuation, as ADTech reports. Suppose the second amplification stage had constant wattage AGC in it. Televes is a well known Spanish TV Antenna Manufacturer who has been in business for a very long time
