DB8e or DBGH

Hi to all.Would like to know it is any good reason to change my DB8e to DBGH any of the DBGH.My problem is i have 38 Chanel but if i turn the DB8e i could get more different station.Now i got the middle,so i could got all my favorite.
When i build a DBGH maybe a got bigger angle to see more station.Thank you for your time and answer.

You didn't provide much information. You need to post your TVFool RESULTS (enter location, copy/paste Results URL at TOP of Browser), a list of Stations you DO receive, those that are giving you problems and those that you WANT but are Missing. It also helps to describe your local situation, such as what Antenna(s), Preamps, Splitters, etc. you are CURRENTLY using, how many TV drops, single home vs basement in a 10-story Condo surrounded by other Condos (etc), indoor vs attic vs roof mount, density of nearby TREES, on top of hill or in a valley, etc.

In your TVFool Report, I had to click on "PENDING APPLICATIONS" to see Ch20 (5.1) and Ch25 (25.1).
And note that strong CHCH2 (CHCH) on Ch51 (51.1, probably 202-deg from London) is MISSING from TVFool.

So you are getting ALL Stations in TVFool Report from TOP down to WNYO on Ch49 (towards 140-202 deg re True North),
1) Moderate Strength CHCJ (CTV2) on Ch35 (209-deg)
2) Weak CKVR (A) on Hi-VHF Ch10 (345-deg)
3) Weak WBBZ (Ind, MeTV, Heros&Icons, Daystar) on Hi-VHF Ch7 (154-deg)

and subsequently weaker stations in RED/GREY Zones from CIII on Ch17 thru CHEX on Ch12 are DUPLICATES, so presumably you do NOT "Need".

IF you are interested in receiving CHCJ (CTV2) on Ch35 (209-deg), it MAY only require turning Antenna JUST A BIT more Clockwise....OR turning ONE of the 4-Bays so that they point is slightly different OUTWARD directions, as shown in the DB-8e Datasheet, pg 3, pg4 and perhaps pg5:

Ch10 and Ch7 are Hi-VHF Stations, which are NOT being received by UHF-ONLY DB-8e. You are lucky that Ch9 is strong enough that it leaks in anyway. If you WANT to receive Ch10 and/or Ch7, I would recommend adding a Medium Gain Hi-VHF Antenna [NOT easy in a Condo or Appt.]...and NOTE that they are in OPPOSITE Directions if you want BOTH of them....and a simple Dipole/Rabbit-Ears probably won't be enough. If you had an Attic or Balcony Available, I would recommend ONE or TWO of the fol. Hi-VHF Antennas:

You might be interested in a DIY Project, using one of the Hi-VHF Loop Antenna Designs found here, such as Bi-Directional [NO Reflector] Hi-VHF Hourglass-Loop, taller higher Gain Quad-Trap-Loop, or even higher Gain Quad-Trap-Loop+2Bars:
Loop Antennas incl Folded Dipole - ImageEvent

RabbitEars shows the upcoming Channel Changes, most of which shouldn't impact the Antenna system...EXCEPT for WNYB (Ind, Tri-State Christian Network) Ch26 moving to Lo-VHF Ch5...."Sometime" prior to early 2019:

IF you are interested in continuing to receive this station when they move to Ch5, you might want to look at how well the above Loop Antennas work on Ch5....Hi-VHF Hourglass-Loop was Okay....and I'll add Charts to the other two "soonish", but they're probably Okay as well....although Reflector Rod versions are probably going to drop off in Lo-VHF Band, unless I design some Dual-Length Reflector Rod versions....

ARE there any other specific Channels you are have trouble with?????

Thank you again holl_ands for your time,i was lurking around on your site,(image event)and find some interesting thing.FF6 +VDAR, nothing wrong with my DB8e just to look around,there is some info about the harness and i think it could use some improvement. And if i turn one site of the antenna will be loose some Db gain? What i would like to achieve is a wide angle high gain (maximum) antenna.Thank you again.
Second Q: on your FF6 have a huge reflector,and i check M4 all data base those huge reflectors give a real good boost for the antenna.Would be possible to build some big reflector for DB8e or the hole thing would change if i do that.?
