Antennas for Acura and Honda brand cars will handled as a group because they are essentially the same and quite similar. Early Hondas of the late ‘70s to the late ‘80s mostly had the antenna mounted at the left front of the roof and retracted into the A-pillar (windshield pillar/roof support). By the late ‘80s power antennas began appearing on the Accord and all Acuras either standard or optional equipment.

Due to changing market conditions we have not restocked depleted inventory of roof antennas for early Accords, Integras and mid ‘90s Civics. You may contact your nearby car radio shop who can order one from the Harada catalog upon his next regular order. Otherwise the Honda/Acura dealership will have one ready to sell.

Replacement Mast (telescopic element): Original Fit mast available for Honda Accord Wagon 1994-95. Part number MST-HO1. For Accord 1990-93 (1991 EX reported not to fit) please order MST-HO2. (**This is a new item and fitment applications are not 100% sure. We welcome your feedback by trying this item on specified year cars plus beyond the range stated. Non-fitment is no risk as we provide a full refund [item plus freight] both ways!)

All Other Honda/Acura: Because of the different mast diameter, it can be difficult in some (mostly newer) Honda versions, to install our replacement masts: MST-3 and MST-4. But it can be done by removing the spacer around the top of the Honda version and some minor adjustments. It requires some mechanical knowledge, time and tools.Masts at the Honda dealers may be $45-60 but we found Majestic Honda, who discounts them. Click here to visit their web site.

Antenna Repairing/Restoration: These drive mechanisms are not repaired because it is more economical to replace the whole motor mechanism unit. For the tinkerer: We have available at times complete mechanism-only of old SJ-3F or SJ-4F available for just $20 plus UPS. You request one for gears and you get one with good gears but a bad relay for example. If you want the switching & relay parts, we send you one with bad gears. Please see Parts Diagram for your reference.

Power Antennas (Motorized) are available in two ways: Aftermarket or original type (OEM). The aftermarket units are less expensive, "one model fits all" and fairly easy to install. This would be the S-90B (Black only available now) which is Taiwan made and quite durable in daily use. These come with a 6 month warranty and a universal adjustable head, (HK-03) 30 degrees max. Add HK-14, the 5 differently angled mounting "heads" or bezels so you select one and dispose of the rest and end up with a factory look, to the untrained eye. The S-90B is quiet and smooth, much like the original. It has a different housing so you will not utilize the original brackets. It should be ordered with the DIN-4 short 6" coaxial cable to mate to the existing cable in the back of the car. Also some power connector adapters may be used which attach to the antenna then neatly plug into the car's existing harness. Otherwise careful splicing can be done. See adapters HO-50, HO-51 and HO-52.

OEM type power antennas, our SJ-4F (available black also) is extremely robust, almost indestructible, smooth and quiet operation and easier to install when set up properly. SJs are Japanese made and from the same vendor to Honda/Acura. One industrial customer has done cycle testing to 100,000 up and down cycles, far surpassing every other Asian made antenna and matching German made units at twice the price. SJ series carry a 1 year warranty. Our "universal" version of the Honda antennas actually is better with a much thicker telescopic element. The factory installed units use thinner (much easier to bend/break) probably to reduce wind drag, visual effect or for increased replacement sales. Then spacers are added to fill the extra space.


**1995/96 and newer Accords went to a Taiwan made antenna as factory installed and SJ info does not apply. The S-90B will be a better replacement in this case.

Our SJ series come in only 2 lengths. This means the retraction tube is a variable length depending on model. SJ-3 is short, compact and SJ-4 is extra long. Honda and Acura combined utilize aprox 6 different lengths. In order for a quick in and out installation to take place you must get the exact same length in the new antenna as is your original. This allows you to use the factory bracket. Our SJ-3 is usually too short and the SJ-4 is usually 1' to 2" too long, allowing us to modify it for you.

STOCK DIMENSIONS

Antenna Number	Dimension "A"
SJ-3F	6"
SJ-4F	10.75"

To do the modification yourself, you will need a tubing cutter, razor blade and phillips screwdriver. There are some "tricks" involved and we will include them here in the near future. Otherwise you can tell us "Dimension-A" by checking the SJ-4 antenna diagram or ship us your antenna and we will measure it here, unless we simply replace your drive mechanism instead.

** To measure your antenna it should be removed from the car, then the upper collar removed to expose the end of the aluminum tube. This will allow proper measurement of dimension-A. It can also be done while installed but great care in measurement is needed**



When you order the new SJ series antenna you state the dimension and your antenna is adjusted for length and shipped within 2-3 days. You will use the original "head kit" simply transfering it to the new unit, and attaching the bracket off yours to the new one also. The SJ-4 has the coaxial connection ready for your car. The power connection can be done by using our HO series connectors, if available for your car, or splicing directly or splicing the connector block off your dead antenna to the new one. This involves only 2 or 3 wires.

Alternatively, if you don't want to go through the trouble yet want an original quality antenna you can simply omit using the factory bracket and use the included bendlable metal strap to support the bottom of the antenna. Order the SJ-3F.

We are currently collecting data for various Honda/Acura vehicles, for Dimension-A length and will post it here for verification by interested persons.

Note the SJ series antenna replacement masts will always be readily available and low cost, in the low $20 range. Plus they are much thicker as explained above.
