The Metz Communications Manta-6 marine VHF antenna is excellent for masthead mounting applications or for smaller boats with limited room and mounting locations.
Antennae whip and housing are both made from stainless steel and the support is nickel plated to endure salt spray. The UV cap will not crack or discolor from prolonged exposure to sunlight, and every connection is soldered to ensure clear and powerful signal strength.
Two different mounts are available (sold separately) for mounting on a bow rail or flat surface. The whip is also completely replaceable in the event of an accident.

What is the VSWR for this antenna at 156 mhz and 162 mhz? I asked Metz and they said they don't provide this kind of info (?).
I'm sorry to say that I don't know (haven't needed to know) and don't have the equipment to determine it.
I cannot answer that question either. It works and works well for vhf and ais
What cable will be compatible with the antenna. Would Ancor RG8X do the job? Model# ANC-189849 Terminal Style: PL-259 (Listed at JD)
Yes, cable and terminal are correct
RG8X is good to a total length of about 60'. Any longer and the signal loss becomes too great, and then you should definitely shift upwards in size to RG213.
Neil, the Metz as supplied by JD dies not have the SO-259 male end at base (even though this is what is pictured on the website - at least it didn't when I ordered mine about 3 years ago) instead it had an 'F' type connection pin and you will need an adaptor from this to a SO-259 for the PL-259 to fit. I am not sure if the RG8X is video cable, but if so, do not use it, get a data/antenna cable to get best results. The Metz is a great antenna. I have one rail mounted on my yacht and can get AIS returns from big vessels almost 50nm away. Oh, and good luck trying to sort out with JD exactly what pin is fitted to the Metz now, they were worse than hopeless with my questions.
Yes, PL-259 will terminate with this antenna. Your choice on the cable. RG8X is a good compromise VHF cable. RG213 has lower loss but is BIG cable to try to snake through a boat!
RG8X should work fine. RG-59 is also an option. If you are running under 30' from your radio to the antenna neither has much advantage over the other. I'd choose the thinnest of the two.Good luck,Dale
The connector is a standard PL259. Your choice of coax should be based on the length of your run. You just need to ensure that you purchase the appropriate PL259 for the size of coax you choose. We standardize on tinned RG213 for all of our antenna connections so we have a good supply of the appropriate size connecters onboard.

I would imagine any shielded coax with low impedance would work.. I am not an expert so I would suggest talking to an electronics expert.
What are the advantages to a longer whip replacement kit? JD sales the 34" replacement. Metz has 34", 40", and 54" replacements. Is there any significant difference in 34" vs 40" ???
The difference is slight, but the shorter antenna is better suited for AIS applications as it is 1/2 wave at the AIS frequencies. The longer one is a general purpose antenna which is closer to 1/2 wave on CH 16. Either antenna will serve both purposes.

Thanks, I have a 23' recreational fishing vessel. I use the vhf to contact the lock&dams to raise/lower the water as I approach, and I would use ch 16 if off-shore and something happens to me or the boat. The antenna sits on the side of my center console. So it's not on a masthead. Sounds like the longer antenna is a better fit for me.
My antenna is at the top of my 54 foot mast from which I get excellent reception, no need for a longer whip. I cannot speak to why one might longer lengths for a sailboat but it may make a difference on power. Would contact manufacturer.
Not the expert here but I would guess the longer the whip the greater the range. But I would recommend you speak directly with Mr, Metz as I found him to be extremely helpful and knowledgable
A 34" antenna is optimal for sailboats as it is just about 3dB gain. This produces a fairly broad field, so as the boat heels there will be minimal effect on the VHF output. As antenna length increases so does gain, thus flattening the shape of the radios broadcast field. This would be desirable for a fixed antenna, or even one on a car or truck, but as a boat heels the signal strength will vary as the field shape rocks back and forth. Bottom line is that sailboats tend to used 34" antennas, while powerboats tend to use longer (higher gain) antennas.
My experience has been limited to VHF installations with the 34" whip, typically at a masthead or on a t-top. I am not an electronics expert, but I believe functional antenna length is determined by the specific radio frequency. I suspect the longer whips allow users to cut to the needed length to "tune" the antenna. For VHF use, the 34" should be the correct choice.

how much cable is included?
No cable is included.
No cable is included...just the antenna and mounting bracket.
None. You supply the cable.
No cable, just the antenna! That way one can use any pre-existing antenna cable, or choose a new one which suits your needs.
no cable was included with the antenna. the antenna worked well.
The antenna includes only the mounting bracket. The cable length needed depends where the antenna and the radio are located. I located the antenna on top of a 32 foot sailboat mast running another 8 feet to the radio location.
No cable is included. You supply the coax to connect directly to the antenna. The antenna has a SO-239 female connector. This is a very well made antenna!
None at all . . .

I wish I could help, but I can't locate the that came with antenna, if any. My antenna was mounted at the top of a 35 ft. mast. I had to make a custom length cable to run inside the mast.
There is no cable included. I bought 213 cable for my sailboat and can not be happier. Antenna is better than the Shakespeare I replaced and have communicated over 30 miles to other strong stations.
I got antenna without cable, already had cable installed on boat.
There is no cable included.
Do you have a bracket for top of the mast installation?thanks!
Check the Metz web site for the bracket P/N
Sergei,The unit comes (as pictured) with a right angle mount, so if you can make or place a vertical surface you can attach the antenna base to at your masthead all is OK. I didn't have this so had to get one manufactured as an horizontal mount plate. See my previous posts re the SO239 connector being supplied with the Metz.
Bob Y. Sergei, the description they give of the Metz Antenna is misleading if you are buying the brand new antenna. Everything you see in the photo is included. If you are looking for the SS Steel "L Bracket", I've got an extra one you can have. Just pay for shipping. You can tell JD it is OK to get my e-mail address.
Hi! The antenna was not described as having a bracket with it, and we thought we'd have to make our own bracket, but we were glad to find that there was one included in the package when we received it. Good luck with yours. -M. & J.
Great sailboat VHF antenna
I bought this to replace a 17 year old identical unit that had suffered degration of the UV top cap. A call to Metz confirmed that the UV cap was really needed. Metz offered the replacement parts plus a complete new antenna at an attractive price, but since I really just needed an antenna fairly quickly I bought from Jamestown for a slightly lower price.
Nice solid antenna. SWR 1:1.5
Mounted on T-top of my old 17 foot Aquasport center console. Checked the SWR and it was 1:1.5 which is very good for a short antenna.

installed easily had to get connectors
will have more comment when mast is re installed on boat

no connectors or cables
installed quite easily on the boat mast,mast not reinstalled yet hope it will work fine..

Performs as advertised
I'm a licensed Global Maritime Distress and Safety System maintainer and an Amateur Extra (ham) operator. I was a little incredulous at the claim of 1.2-to-1 SWR for this antenna. But sure enough, it tested better than that. It is solidly constructed and measures a dead short at DC, which improves its lightning survivability over the more common DC-open designs.

Fantastic rresponse to critical order
The Manta is one of the best and most durable VHF antennas. My previous one purchased through West Marine claimed to have a sealed choke and have SS metal parts. In one year it rusted and leaked rendering my outgoing signal almost useless....and I had to use my handheld. Other Manta users in my yacht club have had no problem, hence my purchase.
The perfect setup for a windex indicator
After more than fifteen years of service it was time to replace my Metz UHF antennae. I sought out this specific brand because of the past performance and durability. I had a certain mounting location and I also had the requirement that I was going to install a Windex wind vane on top of the Mertz antennae. It arrive in a shipping tube and was in perfect condition when it was delivered. The installation was a breeze. Looks great. I will continue to seek out Metz antennas the next time a have to service my masthead.
I replaced another antenna with the Metz and RG 213 cable. I used an L-shaped bracket on the side of the top of mast and it has the strongest signal in the fleet. TX and RX well over 25 miles.

Great little antenna!!
Works perfect on my 17 1/2' boat. Much better (and cheaper) than a full 8' fiberglass antenna.
