Best way to increase connectivity

tyugedfghrtsfdh · 03-29-2006

I currently have a Senao 2511 card with 2 antenna outs hooked up to a 9Dbi omni-antenna on the top of my boat. I am trying to connect to a network that is up the hill but I get 26% or so signal strengh at best. What would be best in this situation?
An amplifier to increase my output power or something that would increase my recieve sensitivity?
Would adding another identical antenna make it more sensitive?
I'm confused as to what exactly the use of 2 antennas would be if they are both close together like I have read they are supposed to. Would my card only use 1 at a time. Thanks.

Peace

Who's network is this, and have you asked the owner for their input? They may be in a better position to help as they're at the location.

Boats need special antennae. My first suggestion would be to make sure you have a marine WiFi antenna.

Neither. See above. RF amplifiers are not devices to be screwed around with, unless you really don't want children. The fact that you have to ask about amplifiers, means the answer is "No freaking way."

Seach on antenna diversity.

It is the wireless at the marina office. They have a hotspot setup but I do not get the best reception.

Using an omni because I could cruise around in the water and still have a chance at reception theorectically.

I could not tell any difference when I was looking at marine vs. regular antennas. Wind speeds and weather proofing was the same I thought.
Do you know what the difference is?

I will look more into antenna diversity and my card features,
thanks for the quick replies.

I use an old school brick cell phone that probably pumps outs 2 watts straight to my brain ( maybe thats why I shouldn't add anymore) so an amp wouldn't fry me too bad. Anyways I think your right about the amp because I don't need to scream any louder at the AP.

I believe it has to do with backscatter from the water.

Hmm I didn't think it was like putting an antenna on a submarine or something....
Wonder how a marine antenna and a regular one both hooked up to my card would work out.

/spoonfeed on..

Marine antennas, (generally,) are designed to work mounted on fiberglass or other non metallic (non-conductive) surfaces, while the other types are 'expecting' to see the metal surface and use it as part of the antenna. (Usually as a ground plane.)

If you would have bothered to search, I'm sure that you could have found the answer for yourself.

Thanks for the knowledge. I looked at the specs for various antennas and marine antennas and couldn't find a difference. I do have this antenna connected to a fiberglass antenna (VHF) so that could mess it up some.

Really? You're serious? You mean connecting an antenna designed for a completely different wavelength has adverse results? Someone contact the media.

Some? I'm surprised you get anything in the way of signal.

I'm not quite getting the picture here. You have a FG VHF antenna and you mounted the WiFi antenna to it? Or are you using a VHF antenna for your WiFi?

Does it really matter? Either way it's a cluster fuck.

/Sarcasm on

Hey Streak, is it really true that you can hook one antenna to another and get it to work? Is it, huh? hu? huh? Please tell me for all to hear, huh? huh? huh?

/Sarcasm off

I say let the Captain and his fuzzy knuckled monkey T'neal go down with the ship.
