Can't get major channel
 
Can not receive KSLA ( CBS Shreveport , LA in Texarkana.
Receive many other stations from Shreveport, even weaker ones.
All are on almost same azimuth and all are aprox. 53 miles.
Bought a "150 mile" antenna. So why can't I get KSLA?

I wish more folks could be warned away from '150 mile' antennas before they waste their hard earned money. If the antenna is what I suspect it is, a cheap bit of plastic, aluminum and a dubious built-in amplifier, please accept my condolences. I hope you didn't pay much.

Before you spend more money, try moving the antenna to a new location and also try changing the height, both up and down from the present position.

If you exhaust all reasonable options, and find no satisfactory mounting location, consider upgrading to an Antennas Direct DB4E or DB8E.

If you are unable to achieve positive results, consider returning the antenna for a refund.
It will be only a matter of time before the motor/ gears deteriorate.

It is shocking in the modern era such inaccurate marketing is allowed to persist. Are we returning to the 1910 JC Penny catalog with all sorts of untested potions and so-called ailment cures?

Sorry... (rant off)

Maybe if more people would rant, some things would change.

That's the nice thing about standards, though.

There are so many to choose from =D

None of that explains why I get all the others and not that one when they are all on same line and distance

In order to answer your question logically the manufacturer of the antenna would need to publish antenna gain and patterns plus preamp gain, noise figure and overload characteristics. That is all missing, so no one can tell you why the antenna fails on KSLA.

I would simply assume it's in a dead spot for that particular station. Moving the antenna is the necessary remedy. It might take a mere 6" or 6' or 6 yards in any direction.

I have on occasion, received stations from as far as 154- 156 miles away consistently, while not being able to lock on one that is 39 miles away and stronger.

Just the nature of the beast, I guess.

At the end of the day, there is only one Absolut.

The one w/ the olive(s) in it :)

I'm curious.

Your TVFool map is only resolved to the block level. It's probably good, but it would be useful to prepare a more accurate version. Go to Online TV Maps, enter your address and click "Map This", then switch to "Satellite" at top right, zoom in and move the red pointer so that it is over your house, set the antenna height and let it update, then click on "Make Radar Plot" and post that link here.

In the end you'll probably want to upgrade to a better antenna.

Above the Peak of the Roof in such a manner that the roof and building do not , obstruct , impede , block , reception in the directions of , South , South West.

Install a , Antennas Direct , DB8e antenna aimed at about 190 degree magnetic compass direction.

http://www.amazon.com.

Here is how to aim antennas , http://www.kyes.com/antenna/pointing/pointing.html.

Use a Real and Actual magnetic compass to aim antenna , do not trust a , cell phone , tablet and etc. compass.

-----------

As a Test to Prove Reception connect a New Continues Length of Coax to the DB8e antenna , and run the New Continues Length of Coax through a Open Door or Window Direct to 1 Tv , No couplers , No splitters , No amplifiers , No etc. .

Digital Tuners can develop -Digital Glitches- that are not cleared out with simple channel scans.

To clear tuner do Double Rescan.

http://www.wchstv.com/DoubleReScanAlert.pdf.

-----------

As always , trees and tree leaves , plants and plant leaves , have a Negative Effect on Broadcast Tv Reception and so do buildings and other obstructions including your own roof and building.

Some and not all Negative Effects are.

Absorbing and Blocking Broadcast Tv Reception.

Multi-Path Reflecting = Tv Signals Bouncing All Around.

The Best Practice for Reliable Reception is to install the DB8e antenna at a location that has the least amount to no amount of obstructions of any type or kind in the directions of reception including your own roof and building in the directions of reception.

------------

A antenna system amplifier will most likely not be required for 1 or 2 Tv's connected.

------------

How many Tv's are/will be connected??

------------

Here are some and not all above the roof antenna mounts.

http://www.ronard.com/909911.html.
Use the , ronard (911) , 5 foot tripod antenna mount.

http://www.ronard.com/34424560.html.
Use the , ronard (4560) , eave antenna mount.

http://www.ronard.com/ychim.html.,
Measure around the chimney and use a , ronard (2212) or ronard (2218) or ronard (2224) .
