Hybrid + Mil Whip for maritime mobile

OE1HTB

Hello to all,

I am new to the forum as well as to Chameleon products.

I have recently purchased the Hybrid base and the Mil for occasional portable use but would also like to use it for /mm when on a trip with a sailing yacht. Do you have hints, tips, any comments or even experience when using it /mm?

Many thanks, 73

Thomas,

To install a HYBRID with a MIL for marine mobile you'll have to do the following:

Find a great location where nothing will hit the whip while navigating.
Ground the base of the HYBRID (the 3/8-24 bold) to any metallic surface of your boat. If your boat does not have any metallic surface you can install the following: KISS-SSB Ground Plane http://store.seafaring.com/index.php?main_page=product_info&cPath=240_249_260&products_id=11665&zenid=7u72a1goqb3o2bu3l8nu7dfhh4
Make sure that the coax cable is sealed with some marine sealant.

You can use the HYBRID with the 30' wire for an End-Fed installation. Simply attach the end of the wire to your upper part of your mast.

Has any body tried using the HYBRID with the 30 foot wire, did you use and special configuration?

I will be setting up my second hybrid with the 30 foot wire, which if straightened out is closer to 31 foot, with my 31 foot fishing-pole/Jackite-kitepole as a vertical. Have already 4 radials/counterpoises 31 foot long buried already as well as a 8 foot ground rod. I am out of state at the moment, but will post my results and set-up on CHA Hybrid forum section by end of week. Had a 31 foot wire vertical with 4:1 balun that worked OK but was rather noisy on all bands compared to my Hybrid-V1 setup.

I have the HYBRID set up as an inverted V, end fed. Overall length is ~72' with the peak of the V being the end of the original 30' wire shipped with the HYBRID. It works great. I initially had it at ~60 feet length and then put a MJF-209 on it and learned I needed ~12 more feet to be tuned to 40m SSB. I get 1.75:1 SWR @ 40m and 2.0:1 SWR @ 12m and 10m without a tuner. Installing 20, 15 and 10m diaginal radials are next. It tunes to 1:1 on the internal meter of my Kenwood 480SAT on all bands with the internal antenna tuner. It really works great. I will send pics as soon as I get around to taking some.

Thank you for the reply.

I plan to mount the hybrid base to the stainless stern pulpit using the claw or an angle iron, this should offer quite a good grounding, but I am a bit concerned about the stability of that construction.
Running radials inside the hull (even the KISS ground plane, sounds interesting but with ~130$ quite pricy and not sure if available in Europe) might be difficult for a short trip where I do not want to dismantle parts of the interior of the hired boat to get close to the hull, but radials inside is for sure the best solution. If the stern pulpit offers not enough grounding (it should be anyhow connected to the ships grounding) maybe an addtional grounding wire will be thrown into the seawater.

As always with installations on ships, also my main concern is the metal of the rig and all the cables (mast, forestay, backstay, shrouds,...). Also mounting the endfed as a free swinging wire to the top during sailing might not be a good option except when anchoring (but then you are no /mm anymore ;) ). But I am quite confident that the vertical Mil whip mounted as far as possible away from the rig will bring good results.

I will give it a try and experiment a bit when onboard later this year.

More comments are always welcome.

Thomas,

I have some concern about mounting the base of the HYBRID to your SS pulpit. The HYBRID seems to work best mounted on a non electrical pole, like fiberglass or wood. That way you can either RF ground the base of the HYBRID or not , whichever seems to provide lower rcvr signal noise and/or better SWR. The base of the HYBRID is ideally looking for an RF ground, like radials and/or tuned counterpoise, not necessarly an electrical ground, although an electrical ground always helps to keep you from getting hurt. The KISS Ground-Plane acts like radials and/or counterpoise.

Just some of my thots, 73, ...Joel

Hello Everybody

And sorry for my English !

Like Thomas, I'm looking for a setup for my sailing boat (/MM) and I think about something easy to install and uninstall. So, the hybrid + V1 + Kiss-SSB seems very interesting for me.

But I have a question :

Do I use an external tuner or the internal turner of rig is ok to adapt from 40 to 10 meters this config ?

Thanks a lot.

External antenna tuners will always serve you better as they've a higher impedance matching ratio than internal one. SO an external tuner will be the best for you and you'll be able to cover 6M to 160M with the HYBRID + V1 + Kiss. I'll recommend you the V1L instead of the V1 on your boat because the V1L is made of aeronautic alloy and stainless steel. The V1L as a slimmer silhouette and is stiffer (bend less) than the V1. So the antenna will be more stable and vertical to offer the best marine communication. The V1L is about 40%+ lighter than the V1.

PierreF8APV

ok Carl and thanks you for informations. In fact, I already have a tuner but not for coaxial feed antenna : it's the SGC230 autotuner. Do you think it's possible to use SG230 with V1L ?

Maybe V1L connected to hot point of the SGC230 (without hybrid) with a wire and the kiss conterpoise connected to the ground of SG230 ?

Carl

If you use the SGC-230 you'll have to create a small coax jumper of about 12" between the tuner and the HYBRID. The shield of the coax will be connected to the tuner ground and the hot wire of the tuner to the center of the coax. Ground your tuner to your vehicle and everything should work fine.

PierreF8APV

ok Carl. I will try this...

Thank's a lot.

Best 73.

We have the dealer Wimo for Europe and I know it's a good one but they don't sell the V1L, only V1.

is there another dealer in europe who sell V1L+MIL+Hybrid ?

Carl

No. If Wimo don't sell the V1L send us an email and we'll take care of it.

PierreF8APV

Ok Carl. I will send an email to wimo. the Wimo Website proposes only V1,V2,V2L,V3 and V4. I inform you as soon as I know...

PierreF8APV

Good news : Wimo have one V1L in stock, so it's ok : I just order the package. Review in few weeks for /MM usage of V1L+Hybrid+SG230+Kiss...

Hello to all...

Some feedback about Hybrid+V1L+KISS-SSB on my sailing boat.

I use the internal tuner of the Kenwood ts480 and it works well from 80 to 10 meters. I left Deauville Marina (North West Coast of France-English Channel) few days ago and I sail along the french coast until the weather let me cross the English Channel.

Everyday, between 3:00AM and 4:30AM UTC, I'm QRV on 30 and 20 meters as F8APV/MM and on 10 meters around 4:00PM to contact some french friends who are located on "Côte d'azur" (French Riviera).

Up to there, I had contacted only European stations but this morning on 10.115, a station from Chicago gave me a report of 559. On 20 and 10 meters, the contacts are made with better report generally. I use only 50W all mode and all band. I will inform you of my next tries with the 9 meters wire !.
