Combining tv antennas

my plot is

http://www.tvfool.com/?option=com_wr...9038eeccf587af

having problem with channel 28. Signal is 50 to 65 in strength.

When attaching tv antennas, should they be attached in a "series", not parallel?

Hello, user name

Thanks for the signal report.

Is that WFPA? It is one of your weaker channels. What are you measuring the strength with? What do your good channels measure? Are you using a preamp?

The title for your thread says combining, but your question says attaching.

What two antennas are you attaching, and why do you want to attach them?

There are many ways of attaching antennas. Do you mean attaching them to the mast or do you mean connecting the coax cables together?

I see a lot of trees in your area that can block TV signals. Are there trees in the signal path from channel 28?



Please tell us more details so that we can give you good advice.

2 large uhf antennas using coax
maybe 3 large uhf antennas using coax if necessary
trying to combine antennas, using coax, to increase overall gain.
using digital to analog converter box to find signal strength
strong stations such as channel 6 are ok
I and antennas are in the attic

Read the above link. Perhaps it will help understand stacking antennas.

so combining antennas in series ............

So combining antennas in series won't work?
Combining must always be done in parallel?

I know how to connect batteries or resistors in series or parallel, but I don't know what you mean by connecting antennas in series or parallel.

I can't answer you question until I know what you mean by connecting antennas in series or parallel.

Can you draw a diagram to show us what you mean?

You can combine two IDENTICAL UHF antennas aimed in the SAME direction with a splitter in reverse for more gain; the two coax lines from the antennas to the splitter must be the SAME length.

Or you could buy a large high gain antenna like the DB8e.

No just go with a king Jack it will out perform that hi price lol
With a built-in sign finder 32dbg.And it's not just uhf?
It all so a hi&low band Vhf.That receive ATSC,03
Come on antennas Direct marketing just uhf tv antennas
Like the 91 XG,IS THE BEST ANTENNA TOO BUY!!WHEN IT COMES
TOO UHF?BROADCASTING TOWER'S,WITH A CHANNEL MASTER 7777AMP
YOU WILL RECEIVE WITH THE ANTENNAS DIRECT 91XG,90miles with it
And less of a wind sail.And a better price and free shipping and don't forget
The tilt feature on that 91,too get them broadcasting tower's this antenna
Will OUT performan the Db8,all the way around.lol no stacking boy that is a lot of money
For DB'8'S .ps I suggest that the trees are a problem that is why I suggest the 91,
And get the ANTENNA up about 40ft off the roof linen or get a chainsaws lol
And the Db8,is not a good idea

I see the words, but I can't picture it.

This is the only way I know how to do it:



The above method uses off-the-shelf parts, but there is also a lowest-loss method for an additional 0.5 dB gain, and it requires special DIY connections.

Whether it's db8 or 91 XG iT's the only way too
Put 2 of the same antennas together!!
In less you have an amp with 2uhf in then
It you can do it that way too.
Good luck 3,Feet apart frum one another
And see if you can adjust the ANTENNA to a 35,DGAGL
Will all so help out with your receive.
