RE: Replacement for Concord Electric Series 90 TV Antenna
Sorry Bill. I should have been a bit clearer. I meant to quote only your statement about the Concorde booster being inside the coach. The power inserter that I mentioned is not a booster but is used to send 12 volt up the coax to the booster in the antenna head. The Concorde booster can not be used if the replacement antenna has a built in booster.

RE: Replacement for Concord Electric Series 90 TV Antenna
I have both a Winegard Sensar IV and a Jack. The Jack is mounted on a Winegard crank-up assembly. I camp virtually 100% in the boondocks, mostly in TV fringe areas. The Jack is useless for VHF stations. About 25% of the US TV stations are broadcasting on the VHF band so VHF is important. My Batwing is mounted on a separate mast and I use that for times that my Jack will not pull in the desired station. The Jack works well for UHF and most times that is all I need.
As Bill noted, the booster is inside the coach. You can not use this booster. If you use the Jack or Batwing, you must use the included power inserter.

Connect all three pins. Circuit board is double sided so traces can be on both sides.

RE: Replacement for Concord Electric Series 90 TV Antenna
About the only RV antenna that has remote positioning is the Winegard Rayzar Automatic for about $400. If you can manage with manual positioning I would recommend the Winegard Sensar IV. It is considered the best RV antenna. It is about the only RV antenna that receives both the VHF band and UHF band well. The Jack does a poor job of receiving the VHF band. It will work for VHF if you are close to the TV transmitter sites but is a poor choice for fringe areas.

RE: 12 v to 12 v trickle charger
Your 2.0 volt differential claim, is simply absurd, and shows you have Zero experience with such a product. Perhaps long ago with older less efficient transistors a 2 volt drop could be expected, but certainly nothing like offered in Mr wizard's link.I'm a retired electronic tech and have worked with many types of power supplies. Granted, my experience may be a bit dated, but the simple fact is you will not be able to charge a 12 volt battery using a 12 volt source. The charge voltage has to be higher than the battery voltage. Even if the voltage differential was zero volts you will never get more than 12 volts out of the buck converter. The specs for the buck converter that MrWizard mentioned are:
Input Voltage: 6V to 40V DC(10V to 40V is suggested)
Output Voltage: 1.2V to 36V DC
The output voltage will never be higher than the input. At the high end the voltage differential is 4 volts. At the low end it's 4.8 volts. At mid range the differential probably is much less but will always be greater than zero. The simplest solution is to use a boost converter.

RE: 12 v to 12 v trickle charger
Drok dc to dc converter
https://images-na.ssl-images-amazon.com/images/I/61u8CjciEkL._SL1001_.jpg width=640This is a buck converter. What is needed is a boost converter. A typical buck or boost converter needs a two volt differential, meaning for 12 volts in a buck converter will have a maximum output of 10 volts. For boost the minimum output will be 14 volts. Or you could get a buck/boost converter which will function as either with no voltage differential.

RE: 12 v to 12 v trickle charger
Expanding on MrWizard's DC-to-DC converter idea, you could make your own charger by using a boost converter connected to a cheap solar charge controller.

Set the boost converter output to about 20 volts and the charge controller will prevent overcharging the battery. Connect the battery to be charged first then apply power to the converter.

RE: Winegard Wingman
EDIT--now that I have played with putting the Jack on and off, I think you can just put the batwing with Wingman on the other way around so the Wingman sticks out the other side.The Batwing can not be turned around.
When I installed my Batwing there was no room to stow it to the rear so I mounted it so it stows to the side. It has been this way for 9 years and have had no problems.
The Winegard Sensar IV aka Batwing is considered the best RV antenna. It has the best VHF performance of the lot. About 25% of US TV stations are now broadcasting on the VHF band. Because of its small size the Jack does a poor job of receiving VHF. Here's a link to an extensive test that SCVJeff did a few years ago:
https://www.rv.net/forum/index.cfm/fuseaction/thread/tid/27171026.cfm
The Sensar Pro is a great improvement over the basic wall plate but is not required. It has an adjustable amplifier that can give you 10 db more gain and also has a display for signal level which allows you to find the best direction for the antenna.

RE: Need Good Sources for Quality Bulk Solar Cable
If this is a permanent install you don't need connectors. Just wire direct from panel junction box to combiner box. Any connector will add a bit more resistance to your run. If connectors are needed, I would suggest using Anderson Powerpull SB50 connectors. The contacts can be crimped or soldered.

RE: My generac diesel generator only runs with prime button
Since the generator runs while the prime button is pushed, this pretty much rules out a fuel problem. The following is info for a 75D model:
Engine starts then shuts down when Start/Stop switch is released.
I assume that the Prime button ties in with Start/Stop
Engine oil level is low.
Defective Low Oil Pressure Switch.
Defective Coolant Temperature Switch.
Defective Control Module circuit board.
Coolant Level is Low.
Defective Low Coolant Level Switch.
Defective Start/Stop switch.
No A.C. output.
Defective engine control board.
If no A.C output:
Reset main line circuit breaker.
Generator internal failure.
Generac discontinued manufacturing RV generators several years ago, so servicing and obtaining parts will be a challenge.

RE: Jayco TV antenna
So when I turn on the booster and get a few pixalated pictures and 2 stations nothing else to do but get a satellite.You most likely need a better antenna. The Winegard Sensar IV is considered the best RV TV antenna. You will have to drill a hole through your roof to install it. The instructions say to install it so that the antenna stows to the rear. This would not work for my installation so I positioned it so that the antenna stows to the side.

RE: 50" - 55" TV... Uses 55 watts or less.
Usually the labeled watt rating is a peak value. The average would be less. About the only way to know the typical wattage is to plug the TV into a meter like a Kill-A-Watt.

RE: Will solid state batteries change the world?
The biggest problem is "refueling". You can fill up a gas powered car in a few minutes. It will probably take a few hours to top up a battery powered car.
