I Am just now playing with a new to me Xtreme Signal 8-Bay VHF/UHF HDTV Antenna (Silver/Black) (HDB8X) BOW TIE elements that AMAZON has on sale for around $60.
This is looking very promising for my 'FREE' BROADCAST channels coming out of Washington DC some 50-60 miles away. DC has their their transmitter cluster on both sides of the town and this BOW-TIE antenna is capable of pointing in two directions at the same time with reduced gain.
First setup on the peak of my north side house roof maybe 15-feet above the ground gets all of the Washington DC BROADCAST stations (around 40 channels) just fine with a single one-direction pointing with one four bow tie group offset just a tad.
I did have to add one of those RCA TVPRAMP1R PRE-AMPLIFIERS (AMAZON) on the pole just under the BOW-TIE PANELs. This is powered-up by the antenna feed line using a 12VDC INSERTED signal plugged into 120VAC in the house. Much the same as the BATWING antenna DC POWER insertion is accomplished on the TTs.
You might want to look into one of these setups for your permanent setups....
I would imagine if I raised my trailer crank-up BATWING ANTENNA to around 15-feet high it would do the same performance. A $90 long VHF/UHF YAGI from LOWES would equally work as well. The HIGH DEF DIGITAL TV Channels start around CH 7 and up into the UHF TV Band. Most of the new FREE BROADCAST digital channels are in the UHF TV BAND now.
