I apologize, I was thinking at some point, that the V-III Amp was overdriving, and it wouldn't be used.
Then, the Dual setup of the V5 and a UHF Antenna (now presumed to be a 4221) both directed to 45° Azimuth. (with the SD-3700)

That not withstanding, are we not duplicating the UHF here, with the 7696 and 4221, or will they will be pointed in different directions.
The 4221 toward the CW station at 214°, and the 7696 to 45°? Will the V-III let the UHF of the 7696 through if it's on the VHF side ?

You sure that V-III shouldn't go completely, or, be replaced by a single in/out Amp with a Combiner ahead of it ?

Have a good Day !
S.W.

styxfix, It sounds bizarre that channel 11 is the actual 28-1, which is the channel we watched prior to installing the preamp? Anyway the winegard 7696p is on the way. I'll be installing it sometime next week. I'll keep all posted.

Houston, I intend to use only the 7696p with the Blonder tongue amp which has two 300 ohm inputs with 1 single coax out. The antenna mast is to fragile to hold up two antennas in heavy wind. BTW is there a solution to the icing of the antenna elements during winter rain conditions?

acamus,

Ok, I think that's a wise choice. The 7696 will do everything that the CM will anyway.
But, you should try it just by it's self first, see how that works, and add the Amp IF it's needed (it probably will be) but try the Antenna alone first.

When/IF you need the Amp, how had you thought to hook it up (the Antenna Input). Run a Twin Lead to the UHF and VHF connectors (2 300 ohm wires) ?
Or maybe just a jumper from one to the other ?

I don't know of any specific way to handle the Icing problem, let me look around.

Have a good Day !
S.W.

Houston,
You assume correctly, two 300 ohm wires from the antenna connections to the preamp, then a single coax to the power supply. Other than saving power, is there a reason you wish to use the 7696 by itself?

Acamus, are you aware that the 7696 is a 75 ohm antenna?

NSAA,

I can not come up with a good enough Pic of the...
Winegard HD7696P
or in the..
Spec Sheet for the Winegard 7696P
to see the Transformer section clearly. In the...
Winegard Series 769 Antennas Installation Manual
on Paragraph 8, it shows the 75 Ohm Cartridge to adapt for Coax, but, it's possible that there may still be connections for 300 Ohm there.

acamus,
To finish the above statement, MOST Antennas have a Balun (matching transformer 300-75 Ohm) which one can electively remove, giving the user an option to use Twin Lead 300 Ohm, or, connecting the Balun, to adapt 75 Ohm Coaxial cable to the Antenna. Your choice to go with 300 Ohm, wold have required you to not use the Balun.
You may have already known this, but so many people read these posts, I've found it helpful, to be basic most times.

You ask, "is there a reason you wish to use the 7696 by itself?"
Yes, I can't help but think about the possible Overdriving issue !
It would be a simple "trial", to use the Balun and a Inline Connector (coupling) to bypass the Amp, and see if the 7696 wold provide adequate viewing on it's own.
It is a higher gain and more directional Antenna than the 4221, and I think you should at least give it a chance, and see what it will do by it's self.

If NSAA's implication is correct, you may not have a choice but to use a coupling like the...
Winegard FS-8100
and a short piece of Coax, to reach the Antenna, unless there is sufficient slack in your Downlead, to pull it up to the Antenna directly.
I've linked this for the Pic only, the item shown is a Bag of 6, and you would only need one of them, which you may have already, or buy locally.

Have a good Day !
S.W.

Houston,
Your point is well made. I do have several coax to coax adapters on the shelf. I can't help but think your suggestion of use without preamp first is a good recommendation. Fewer parts, less noise. Sure I'll try it first. It will be some extra work but it could prove to be worth it. I'll keep you posted.

I have been offline for a couple of days, so forgive me if this has already been mentioned as I just skimmed over the posts I've missed.

The only issue I see using the existing V-III pre-amp with the 7696 antenna, is that the V-III was designed for 2 seperate antennas. That is the reason for the two independant inputs. The 7696 only has 1 connection point, be it 75ohm or 300ohm. So you will still need to jumper the UHF to the VHF.

Splicer,
I'm going to go with Houstons suggestion. Without the preamp first. I'll adapt with connectors later if necessary.
