dual-band mobile antennas

Fold-Over Hinge

Most Comet mobile antennas over 29″ length have a fold-over hinge built into the base section of the antenna. It is NOT an automatic fold-over, you must manually lift the element up out of the socket and lay the antenna whip down in order to enter garages, parking structures etc…

 

It is important that you lift the whip completely up and out of the socket before folding the hinge.

 

Like any hinge, it will BREAK if it is folded the wrong direction. The hinge rotates 360 deg inside the socket so it will fold in the direction needed.

 

Many Chinese and other look-a-like antennas have very annoying problems associated with their fold-over hinges. The most common is a weak spring. The antena lifts up and out of the socket all by itself at highway speeds! The antenna is unusable when it is laying down and most users need to defeat the hinge or constantly adjust the angle to keep it vertical.

 

And to be honest, Comet had this problem “initially” as well! The weak spring was almost always a problem with the larger antennas so Comet engineers went to work and re-designed the fold-over. Our larger antennas now have a threaded collar around the hinge: Loosen the collar, lift it up, and the hinge is exposed. No more problem.

 

**WARNING**Many antenna companies have now copied the Comet fold-over design but many have avoided making the improvement to save the cost.

B-10
B-10NMO

DualBand 146/446MHz mobile antenna
Very short yet efficient antenna, mainly used in metropolitan areas where extended range is not critical.
Particularly used in a city or area where the repeater sites are generally higher than the mobile station due to the pattern having an uptilt.

CA-2x4SR

BROADBAND VHF/UHF Dual Band Antenna

Dual band, designed to assist Search & Rescue Volunteers and Professionals
1.5:1 or less SWR:
144-148/440-450MHz
2:1 or less  SWR:
140-160/435-465MHz
Gain: 3.8/6.2dBi
Max Power: 150 watts
Length: 40 inches
Connector: PL-259, fold-over hinge included

 

The CA-2x4SR is a broad-band antenna designed for those needing voice communications on the ham radio, public service, land mobile, and FRS frequency ranges.

 

When the amateur radio community is working together with local search and rescue and other public service agencies, the CA-2x4SR antenna allows TX and RX capability in both bands!

 

The coverage area and gain provided by the CA-2x4SR is remarkable. Whether used on VHF or UHF or both, it is an asset to the communications needs of amateurs and land mobile users simultaneously.

CA-SPR

NEW!! Optional spring for the CA-2x4SR and CA-2x4SRNMO

 

The CA-2x4SR and CA-2x4SRNMO antennas are relatively stiff due to the phasing sections Comet uses in the radiating element in order to make the antenna both broadband and high gain.  Because these antennas are used by Search and Rescue teams off-highway as much as they are for traditional on-highway use, customers have often asked if Comet would ever make a spring that could be used with them to add some flexibility.

 

The CA-SPR is Comet’s answer to that request. Rather than include the spring in every antenna, they made it an optional item that can be added to an existing antenna without the expense of purchasing a completely new antenna.  The CA-SPR basically replaces the lower element and takes only a few minutes to install.  Adding the spring does not change the SWR or performance but will help it survive brushes with tree branches, low clearance structures, etc…

HP-32FHN

Heavy Duty, High Power, DualBand Mobile Antenna 146/446Mhz

This is the famous HEAVY-DUTY dualband antenna named after the equally famous Ray Davis, KD6FHN.   As one of the founding members of the Motorcycling Amateur Radio Club (MARC), Ray and his group were installing and breaking mobile antennas much too often.  The short wheel-base and high tire pressure of the Goldwings they ride transferred the road energy to the antenna, and they broke far too often  About 20 years ago Ray rode in on his white Goldwing (Casper) one day and asked for help.  Long story short, the HP-32FHN proved to be structurally strong enough to withstand the beating, and a friendship between the charity driven MARC group and COMET antenna was born.  If you run into Ray, ask him about the time he was attempting to ride “Route 66” from beginning to end.  Some of Route 66 is dirt road, his Goldwing’s tires were caught in a rut in the road and he went down…HARD!  His Goldwing was a total loss, but the HP-32HPN antenna was undamaged   Ray is a former Fire Captain, you can also want to ask him about the time his fire station caught fire…but he may want to change the subject pretty quickly!

2M/70cm DualBand antenna on a small magnetic mount

Most mag mount antennas require you to pull the entire magnet and antenna of the vehicle for a car wash, to secure it from theft, etc… That typically ends up scratching the mounting location.  The M-24 radiating element is threaded onto the magnet. Simply unscrew the whip to lock it away or to allow clearance under parking structures, etc… and leave the magnet in place on the vehicle.  Ready to go back on the air?…screw the whip back on.

SBB-1
SBB-1NMO

Flexible DualBand 2M/70cm mobile antenna
The whip section is enclosed in a dense but flexible rubber coating.  Typically this antenna is the choice when it will be mounted on top of a truck, van, or other high profile vehicle.  The height of the mounting location improves the antennas range, but also makes it susceptible to damage from low clearance obstructions.  If you don’t need a lot of range, but you do need an antenna that is convenient, this is a great choice.
