What is NMO antenna mount?
A popular type of antenna mount is called an “NMO” which stands for new Motorola. NMO mounts are devised to have a standard threaded connector where you screw on the antenna of choice to the mount of choice. The NMO mount itself connects to the antenna and provides the antenna cable as well.
What size hole for NMO mount?
¾ inch
The outside ring is threaded to a size and pitch of 1 1/8” x 18. NMO mounts come in various styles and the only difference is how the NMO connector is terminated on the opposite side. As we move from left to right, you will see a NMO mount to be used in a ¾ inch diameter hole with a length of coaxial cable attached.
Do NMO mounts need to be grounded?
Remember..it only counts as a ground plane if you have a good electrical connection between the shield of your coax and the hood at the base of the antenna (one of several reasons to use NMO over mag mounts). 1/2 wave antennas fed in the center (a dipole) do not require a ground plane.
What disease is NMO?
Neuromyelitis optica (NMO), also known as Devic’s disease, is a rare condition where the immune system damages the spinal cord and the nerves of the eyes (optic nerves). NMO can affect anyone at any age, but it’s more common in women than men.
What is a so 239 connector?
The above connectors are used in applications like amateur / HAM radio, CB / Citizens Band radio, Marine radio & VHF radio. Typically, the SO-239 (UHF Female/UHF Jack) is installed ON THE RADIO, and the PL-259 (UHF Male/UHF Plug) is installed ON THE CABLE. The two “mate” and are collectively known as a UHF Connection.
What is a PL-259 connector?
PL-259 Connectors, Adapters & Reducers for Ham Radio Applications. The PL-259 is also known as a UHF connector with the common male/female variants. The male UHF PL259 is the most common connector used to interconnect equipment and antennas in ham shacks.
What is the best dual band mobile antenna?

What is a ground independent antenna?
Ground independent antennas are antennas that have been designed to incorporate in its functionality a simulated ground plane to allow it to perform efficiently with a minimum or no ground plane. These antennas are generally comprised of a minimum of a ½ wave element.
What is the life expectancy of someone with NMO?
Patients with neuromyelitis optica (NMO) patients have a 91% to 98% five-year survival rate. Current research indicates that neuromyelitis optica (NMO) patients have a 91% to 98% five-year survival rate.
What is the best treatment for NMO?
The standard of care for an initial attack of NMO includes the following: Intravenous (into the vein) high-dose corticosteroids (methylprednisolone)…Other drugs used off-label to prevent attacks include:
- Rituxan (rituximab)
- CellCept (mycophenolate mofetil)
- Imuran, Azasan (azathioprine)
- Prednisone.
- Methotrexate.
How does a NMO Mount work on a roof?
The NMO mount has teeth on the bottom piece which make a good firm connection to the metal of the roof top. This is certainly a great ground connection for the coaxial cable shield currents, but the capacitive coupling of a magnetic antenna works pretty well too.
How big of a hole do you need for an NMO antenna?
Nice. Current Antenna with various NMO Through Hole Replacements. Research on the Internet reveals quite a few selections to ponder when considering through hole NMO antenna mounts. Choices include: It is quite clear the traditional installation of NMO uses a 3/4 inch hole.
What kind of Mount do I need for my NMO radio?
One thing that became obvious after reading the forums about NMO mounts is the suggestion to use brand name parts from Laird, Motorola, Larson, etc. The NMO mount is standardized, but the suggestion is quality tolerances may be loose in off-brand parts.
Can a magnetic antenna be placed on the roof?
The magnetic antenna allows perfect positioning of your antenna in the middle of your roof. That’s good. However, when your car looks like this… …it may be time to think of an alternative approach. What about glass mount antennas? I thought long and hard about a glass-mount window antenna.
