Laird. My Laird is less than 7" including the NMO base.

Having a repeater won't guarantee you will be able to talk. Both your radio and the handheld your wife uses have to be able to reach the repeater. The repeater itself has to be operational during whatever emergency that is causing your wife to use it rather than a cell phone or regular landline phone. Just as a figure-of-merit, you are looking at a cost of about $1500 to install the repeater, power and antenna. It can be done for less, but as you stated it is for emergencies, you'll want a repurposed commercial unit over a low end unit manufactured for casual use.

None of these would work. It's a 2019 HSE. I've looked at the Lidos and the only one that could be acceptable is the cup mount but not with two people in the car.

I had that Comet antenna bite the dust when I was in a Chevy. The mount just came off the car when I hit about 60 MPH. The magnet has a good 25 pound pull to detach it from the sheet of steel I have it currently o.

No such place to install a control head in my Discovery. I'll probably have to put it on top of the dash with the radio body in the cargo area.

I know of several jurisdictions under 90.20 that run their repeaters "backwards." One of which is a statewide agency.

Check the Motorola Solutions website for dealers near you. That's the best bet.

As a new ham I find the ARRL useful. The amount of information available on multiple topics makes the dues worthwhile.

With hand-helds a longer antenna will let you receive a signal a little better but do extremely little for improving your talk-out range.

The SWR curve is bell shaped. As you go up or down from the resonant frequency the SWR will increase so your question can't be answered until we know if the resonant frequency is higher or lower than your target frequency.

Other than radio or TV the only service that would want to be high on that tower would be a paging company.

One antenna I like is the Comet CA-2X4SR. It's more than the MFJ but the usable bandwidth covers both ham frequencies and FRS/GMRS. It is available with either an SO239 or NMO mount option.

The mount is a standard 3/8 24 or for an antenna with a 3/8 male end with the thread count of 24 turns per inch. This is pretty much a standard for CB antennas but quite common for dual band V/UHF as well. Where it is isn't the best choice, but will work fairly well.

Michael, Please provide us with your definition of influencer. I saw the post as an announcement with nothing to indicate a person should purchase this item due to his standing in the forums.

No, people are still willing to help but the mindset is GMRS isn't meant for casual assistance like traveler information. A great many GMRS units are used as base stations and people at home usually have little information regarding traffic conditions. The major thrust of CB from back in the 70's to current time has always been a mobile installation with home base stations secondary.

Ahh, spell check doesn't like companders.

I would use the vertical posts on the fence as anchors over the top rail. The top rail wouldn't be made to handle the stress from a lead pulling on it. The vertical posts are probably anchored in concrete and would handle the stress from a guy line much better.

The rules are pretty absolute about what is and isn't legal for GMRS. The truth of the matter is little enforcement is done currently so using a non-certified radio is quite common. Used Business or Public Safety radios can be purchased from many dealers and E-Bay but they aren't as flexible for changing the configuration if a different station/repeater is set up different than what your radio is currently. A lot of the amateur equipment that works in the FRS/GMRS channels can be reconfigured from the front panel or through microphone controls to handle different repeaters on the same frequency.

In the current state of affairs you are more likely to be able to contact another traveler or station using CB rather than GMRS or FRS. A hand held radio, with the supplied antenna inside the car isn't going to reach very far, probably a half mile for certain and a few miles at best. Pair it with an external antenna and you can have an average contact area of 2 to 3 miles. Moving to a mobile unit, you will have the 2 - 3 mile minimum range with a max of 10 - 12 miles with some exceptions. Your best coverage area for travel on the major routes will be cellular. If you are set on using radio, an amateur technician license with a 2 meter HH will give you the most coverage area.

Sidetone is actually a telephony term and it refers to a small part of the input signal being fed back to the speaker.

I think you are both over thinking the monitoring of radio transmissions at the site of an incident. The only comms that are actively monitored would be the non-encrypted ones as tracking frequency hopping or code encrypted comms requires special equipment not found in most incident command vehicles. They are going after the low hanging fruit as it were.

Rather than move the mount, install a jumper wire from the mount to a good ground point. I would recommend nothing smaller than 14 ga wire.

BINT (Back In The Day) I built a line filter using a bridge rectifier and a feed-through capacitor to cure the engine noise into my CB. Doubt you could find the electrolytic feed-through cap now.

For simplicity, stick with the Midlands. There are many other brands available, BaoFeng, BTECH, Anytone, TYT, Woxun and thirty or more brands. There are several on-line retailers as well but BuytwoWayRadios gets good reviews.

None of my radios have numbers assigned to tones so privacy code 07 means absolutely nothing to me. There is no assurance that a manufacturer would assign the same tone to a code number so a value of 7 could be almost any tone that would be compatible with only their radios. GMRS/FRS still isn't popular enough that a significant number of people would even carry the radios or know how to set a code in the first place. CTCSS codes are something I set using a computer for specific repeaters and wouldn't even begin to fumble my way through a menu on a screen or voice prompt to try to set. No, using or requiring a code on a channel for emergency purposes isn't a good practice in my estimation. Perhaps something such as calling on the 7's would be a better solution, as there would be 6 specific times for beginning a call that would (and should) change to a different channel.
