- The GALAXY INFL8-5 by Shakespeare is the world’s first emergency antenna with the performance to earn the GALAXY name. It is a full 3dB inflatable antenna that can be rapidly deployed via a CO2 cartridge or a manual tube and inflates to 5 ft (1.6 m). The INFL8 provides a range of up to three times greater than any existing helical emergency antenna. Thanks to its inflatable design, the antenna can be deflated and stowed away safely in its easy-to-spot storage bag until it is needed again.
The antenna can be mounted with its hook and loop straps allowing for quick and easy installation in any weather to stanchions, outriggers or other vertical structures on board. The antenna also features grommets on the top and bottom to facilitate hanging and securing to spreaders, masts, hard tops and other structures even in case the inflatable bladder becomes damaged.
The connectors included in the package allow for versatile connection options. The pre-soldered PL-259 connector allows connection to a Fixed VHF directly or a handheld via the included SMA Adaptor. The package also includes a solder-free female UHF connector that allows the antenna to be spliced into existing coax cables on the boat.
Warning: 1. Not for use as a personal flotation device.
2. Not for use as a visual distress signal.
3. Not suitable for submersible/ man overboard applications. - Věda a technologie
Nice work Dave!
Replace the CO2 cartridge with Helium and float your VHF antenna up in the sky for more range! hehe
A great piece of amateur radio kit but what is the size or specification of the CO2 Gas Cylinder as i am having problems finding online which one to order as rearming spares for use within the UK?
I am not sure what context this is supposed to be used in. While I accept that it might extend my vhf range, under the circumstances when I might use it I would prefer a (smaller) PLB which has a much greater range- via satellite and is easier to deploy.
So everyone can afford £200 for a satellite PLB, and almost £1000 for the phone? As opposed to circa £100 for this back up/emergency antenna for the radio most should already have?
@@darrenowens8693 Clearly I already have a radio (not sure where the £1000 phone comes in). I think that my PLB will be more likely to work in an emergency than an inflatable antenna as obstructions and distance from a receiver are not issues and of course the PLB provides an accurate position in real time. I get the impression that the antenna is a bit larger undeployed than my PLB (I stand to be corrected). This is an issue, if,like me you feel that these emergency bits of equipment need to be on your person. Out of the last 3 swims I have had, I managed to hold onto my boat in only one. I am glad to say that none of the swims needed rescues, other than from fellow paddlers! I accept that the antenna is cheaper but feel it is less good value.
When someone starts talking about an antenna in terms of "dB" with no further explanation or reference, it's time to stop watching the commercial. Why are you keeping the actual performance a secret?
I had that issue also. Eventually found that it is 0dBd or 3dBi.
@@Steve264511 Decibel readings always compare one thing to another (usually fixed) thing. Decibel readings always compare one thing to another (usually fixed) thing. An antenna by itself doesn't "have" any dBs. The gain of an antenna is usually measured relative to an isotrpic antenna (dBi) or a dipole (dBd.) So when he says it has "3dB", does he mean gain compared to one of those antenna types? We have no idea. A dipole, btw, has 2.15dB gain over an isotropic antenna. You get gain by focusing the radiation pattern, it goes up in one direction and goes down in another. Again, when you see an antenna d that merely says "dB' instead of dBi or dBd (or some other reference), someone is avoiding giving out real information.
