I told my friend in Las Vegas that she should have no trouble getting an antenna signal because TVFool said her signals were all from -24 to -36 dBm Pwr from broadcast towers 21-23 miles away and are all Line of Sight. Instead she is getting terrible reception, with a great deal pf pixelation or no signal at all. However she got a strong signal that TVFool says has a signal level of -78dBm.

I am puzzled. The only thing that I can think of is that the northern part of the Las Vegas strip is directly between her the broadcast tower. The station that is nominally supposed to be so much worse is in Pahrump, which is on the other side of mountains of Red Rock Canyon and just south of Charleston Peak. However, she is getting a strong signal from there.

I've lost all credibility with her so I don't know if I should tell her to get an amplified antenna or not.

With only 23 miles and line of sight, all channels available from the tower should be received with no problem, without an amped antenna.
I receive signals from 40 miles with antenna in the attic over my garage with signals passing thru an oak tree by the street curb.
Is her antenna pointing to the tower as referred on TVfool and antennaweb.org
Check the connection on the TV, the cable and the connection at the antenna.

Too many variables to say for sure.

Yes, if there are tall buildings she could be in a shadow.

Antenna location can be HIGHLY sensitive. Literally a few feet can make all the difference. I walked my property and roof a number of times before setting my antenna.

If the antenna is directional and is pointed in the wrong direction...

I've always found "store bought" antenna to be of much worth. Do a homemade antenna, you will probably have better results.

RCA Digital Flat Passive Antenna $19.88. It was mounted flush to the window facing East, the towers are South east at 118-130 degrees

Antenna Web says A Small Multidirectional Antenna is recommended to receive this station. Look for the CTA-certified Yellow mark on the antenna's box. for 10 stations. The CTA-certification is for outdoor antennas only.

For my home Antenna Web says A Medium Directional Antenna is recommended to receive this station. Look for the CTA-certified Red mark on the antenna's box. However, I am able to tune in the station with just rabbit ears mounted in a basement window.

I told her that Yellow should be a piece of cake. She doesn't have an attic, nor does she have the ability or the money to hire someone to climb the roof and mount an expensive antenna and run wires into the home. Remember that she is desperately ill, and the antenna is a way to save money without giving up television completely.

.
That antenna works well at my Grandmothers, zilch at my house. I picked up a better antenna and I get most of the stations with it.
