Designed specifically for RVs. Ned Moderator Emeritus. USB 2. There are better solutions for less money. OK Ned, I am interested. What do I use in a campground to keep from having to drag my laptop into the office? It has gotten very good reviews. John From Detroit Well-known member.

Option 1: No data service in MH. I very strongly suggest option 3. Ron Moderator Emeritus. Joined Jan 29, Posts 18, Location Home is where we park it. BruceinFL said:. Click to expand Thanks Ned, that unit looks interesting. I have wireless built in to my laptop Apple but it doesn't have enough range for some of the campgrounds so I need a directional antenna. It has the pads for two u. So I am just leaving it the way it is for now. Its a strong APas far as power goes, even deflecting my passive FS meter made with a 1n34 type diode and capacitor.

If you want the panel dimensions I could measure it or scan it for you. That is even easier to make than the colinear.

Just need some copper sheeting and tin snips. I very much dislike when someone intentional is spreading false information in opposite to my already above written information. Both of us can not be right, one of us is lying. I have written that it is a useless antenna design and you is writing opposite. I state that there is no resonance related to wifi for this design.

Even with very simple antenna knowledge is it easy to understand that it is a rubbish random wire, not related to antenna design. No excuse at all, especially as if you says this is an good antenna design, as I then must be wrong. Basic checking if it is an antenna at all is very easy done if you have bent actual wire by yourself. You must have done some kind of check? VSWR value, from where have you got that if you not have done any checking?

One real simple method to check if antenna is working as intended: 1. Connect the antenna to your wifi adapter or router and use free software to read RSSI if such software not is already included. Place hand at antenna above 1:st coil and there will be almost no reduction in performance, less then 2 dB, as these parts not add anything to antenna performance more then any random wire would do.

It proves that these sections are useless and just to minor degree affect antenna efficiency and gain. Remaining antenna bottom section. No clever calculations needed gives that what now remains from above simple test is mainly an endfeed 0. Just by knowing how long a resonant length is can it be proved that this design NOT is resonating at 2.

Rather simple math skills needed. So what is performance for this antenna? It have obviously negative gain due to its high reflection losses. VSWR is not even close to what normally is acceptable.

Lets measure your design. We already expect it to behave similar to an endfeed 0. It is nothing else then a random bent wire, resulting in an unusual poor antenna.

This Smith chart for the actual antenna confirms that this design have an impedance similar to a 0. Just by looking at actual design could that be predicted. Endfeeding a 0. It is not even close to a resonance at 50 Ohm, center point at above Smith chart. So mr cdev, have you measured a VSWR below 1.

Did you misread? It was maybe or as that is closer to a possible truth? One of us must be wrong. You or me? Pages: [ 1 ] Go Up. There was an error while thanking.
