I am currently testing the Televes DATBoss MIX LR.
I am looking at this from the consumer perspective. Not the wild eye hobbyist. Which many of us are.
Now I under stand that there is some contention concerning how Televes arrives at its numbers.
That argument is nothing new concerning any antenna manufacturer past or present.

I would also point out we are beyond the days of the Quantum twin booms and Wade VIp's where materials and material costs are concerned.
Few if any are going to be willing to pay Blonder Tongue prices for a residential antenna when most people today mistakenly believe those silly mud flaps they stick on their wall are excellent antennas.

So with that in mind.


Assembly was easy.
Over all structurally is fairly solid. I noted a couple of mild structural issues that could be addressed with tighter tolerances where the upper and lower booms are concerned.
However most home owners would not even take notice of it.
Otherwise the over all design is pretty innovative and once assembled completely pretty solid over all.
The DATBoss comes with an integrated amplifier. That automatically adjust the gain to appropriate levels so as to avoid any potential overloading.

My first run testing was with my local transmitters. That range from 4.9 and 6.9 miles out.
The topography is steep with intervening mountain ranges.
All the transmitters are 1 and 2 edge.

The second test run will be with my fringe transmitters out to 120 miles.
The First series of test against my Winegard 8200U with a Winegard AP-8700 Preamplifier.

The antennas are the same location and same height. I will lose a little time swapping out masts. It is unavoidable.
The DAT does not have VHF LO capability so any VHF LO Transmitters will no be included.
The Spectrometer I will be using is a Televes H30D3.
I will not be able to provide band scans or overlays with the device.
It will be individual reading per transmitter.

I have not made offsets for any loss in either the coax or the Winegard LS 275C splitter that is feeding the spectrometer and the HDHomerun.

Most will recognize the traces generated by Rabbitears. .


A couple images to provide a base line of information.




At 60 Degrees

255 degrees


Hope fully I will not be creating to much confusion.
In the first series photos are the Rabbitears trace generated.
The traces are devided by where I swapped antennas.
8200U data is on the left. DAT Data is on the right.
Please note the CNR line.

The date on this Data is 8-6-2020
Antenna Aim is at 60 degrees

From the Spectrometer.
I left RF16 because I missed saving one of the readings.

This next set of data came from the morning of 8-7-2020
Antenna Aim Point is 260 Degrees
Fringe Transmitters.
I switched out the DAT for the 8200U
Gap in transmission is the time of antenna swap.

I left the DAT sit facing 260 degrees for about 48 hours so far. 8-10-2020
Keep in mind these transmitters are between 100 - 120 miles out.

Some readings from the H30D3




























3 days with the DAT pointed 260 degrees. 5 Transmitters decoding virtually uninterrupted.
You can see where I started playing with the DAT on the 6th.

Wow you went to a lot of work to produce all this data! Can you now summarize what it all means?

Quite simply the innovative design of the Televes antenna combined with its Tforce technology, which has the ability to automatically adjust its gain to meet signal demand works.
While it is not a solution for VHF LO. Its smaller and more compact design both keeps up with and exceeds the 8200U when used in the local conditions that I experience.

While it cant be an apples to apples comparison because of the differences in technology. What matters is the results you are achieving as you cross the finish line.
