Personally a BIG part of my (ample) viewing time is spent watching "THE CW" on XETV from Tijuana:
XETV-DT on RF Ch23 will be the most difficult to receive, so I would recommend a Very High Gain UHF Antenna, such as a relatively easy to conceal 8-Bay Bowtie. Since it is technically a bit bigger than 1-meter (esp. on the Diagonal), you can hide it with some PLASTIC or THIN WOOD material, such as a simple curtain or a fake hanging plant (NO metal) or inexpensive garden lattice or decorative panels such as following:
If you don't have an easy way to hang the antenna on your balcony (ABOVE the railing, pointed towards 166-deg True North), you might want to use a fairly heavy potted plant and a 6-8 foot mast. One or two spikes through the bottom of the mast (in the potting soil) will prevent rotation in the wind.
Fol. On-Air test found (newer) Channel-Master CM4228HD had about 2 dB more Gain on Ch23 & Ch24 than Antennas-Direct (older) DB-8 or Winegard HD-8800 (aka PR
New Antennas-Direct DB-8e wasn't included in this test, but modeling results in their spec sheets show a significant improvement that are at least equal to specs and modeling for CM4228HD, so I would consider it a close alternative, but we don't think it works very well in Hi-VHF Band:
Size of CM4228HD: 36" H x 40" W x 4.5" D
Size of DB-8e is a bit bigger: 37" W x 50" W x 7.5" D
Another (even larger) alternative which outperforms these antennas is the DIY (Do-It-Yourself or kit form) mclapp M4 Super-4-Bay Antenna:
Size of mclapp M4 (10x9.5): 36" H x 40" W x 4.5" D (same as CM4228HD)
If you find you need just a bit more reliability receiving XETV, a Preamp (e.g. Winegard AP-4700) can provide a bit more sensitivity when used on the UHF (only) Antenna. Power to the Preamp goes up the Coax, so no additional wires. Don't amplify Hi-VHF signals due to close proximity of interference from FM transmitters on Mt Woodson (above Poway Lake).
BTW: Most DTV stations from Mt Woodson are foreign language, etc and might not be of any interest to you.....and would be difficult to receive anyway....
More info re 8-Bay and other alternatives:
If you decide you want a less expensive UHF antenna, you could TRY (and return if not satisfied) one of the 4-Bay Bowtie antennas, such as Channel-Master CM4221HD (24" H x 30" W x 7.5" with Balun Hack), Winegard HD-4400 (aka PR
-4400) or the slightly different (circular element) Antennas-Direct C4 (20" H x 28" W x 4.5" D:
Hi-VHF Band reception of CM-4228HD has been confirmed in fol. On-Air comparison test:
Direction of Ch8 & Ch10 (226-deg TN) is 60-deg away from mid-point (166-deg TN) of XETV (Ch23) and the other major Networks (Ch18/19/30/40) on Mt Miguel. CM4228HD has moderate Gain on Ch7-13 (except not so much on Ch9), but Gain toward Ch8/10 will be lower, about +3 dBi on Ch8 and +6 dBi on Ch10...which is slightly better than a Rabbit Ear Antenna. [See Gain 60-deg away from Forward direction in CM4228HD Hi-VHF Azimuthal Pattern Charts.] Note that none of the other 8-Bay or 4-Bay Antennas mentioned above provide significant Gain in Hi-VHF Band....although the DIY mclapp M4 Super-4-Bay Antenna provides about +6 dBi on Ch8/10 when 60-deg off-axis:
If you decide to use a separate Hi-VHF Antenna, such as Indoor Rabbit Ears, you'll need a UHF/VHF Combiner to combine the signals from the two antennas (do NOT use an RF Splitter in reverse). Available as Pico-Macom UVSJ, Holland UVSJ, Antennas-Direct VHF/UHF Combiner and Radio Shack 15-2586. Only the Radio Shack and Antennas-Direct UVSJ devices are compatible (DCPASS on UHF Port) with a UHF Preamp when UVSJ is placed between Preamp and downlead coax (preferred for best sensitivity). If UVSJ is placed between UHF Antenna and (UHF + VHF Passive "Bypass") Preamp, a small 0.5 dB loss of sensitivity will occur, but ANY UVSJ type device can be used.
