hey i think u guys have got like really great ideas and well did anyone think of trying to like ask ppl who know about this kind of stuff or like look up sites on it cause i bet there are like a million sites

Ok, back on like page 5 there was a post about a thread in ausimicro about removing crip caps and all the different types of controls. Was wondering if someone could post a link to it.
I have a new Booster car and a Wild Char-g both with crappy range I want to see if I can remedy..

one note regarding the tx...
i've tried 3.6v to the TX instead of the
standard 2.4v and it does increase range on my 45mhz lxx...
however, running with the 3rd cell on the tx also increases
the charge voltage.
...
to accomodate for this (those running single cel bits)
i used the switch modification so that i can switch
between 2 and 3 cell tx power....
basically, i use 2 cells to charge, 3cells to control
the car...
...
can't give exact measurements on range yet,
but from what i've seen, my car stutters consistently
when it runs next to my kitchen fridge and i am about
12 feet away....
with 2cells powering the tx, it stutters
with 3cells powering the tx, i get full control......
have yet to install the telescoping antenna at this point.

I've a few Ideas and wondered if anyone cared to try them or was interested anyway.

I was thinking about the "nokia phone antenna" issue, and was curious, if you could find a way to just use copper wire, say put a very thin layer of sticky tack or something along the inside of the body in order to make your "zigzags" with the copper wire, how effective would that be? (you may be able to get more zig-zags in there, but i don't know the effectiveness of it in general)

Also, another Idea would be (going along with the nokia theme here *grins*) I've got an old phone antenna, the kind that you plug into the phone and attatch to your car with a magnet? I just found it today actually... And I wonder if you could change the type of hookup then make a "plug-in" for your controller!

I'll try to draw what i mean soon!

blownPT · #**203** 03-11-2003, 08:52 PM

here's a drawing...

The antenna has a wire and a shield. that would be perfect for a mono phone plug and jack.

I don't have them handy, so right now I couldn't tell you where to make the connections. and I can't do it now because I'm at home and my controller is at college. Will try next week.

I was thinking the advantage here would be if you were just racing or playing around in a room.

If you don't mind being tethered, you could have range over most of the room with the dual antennas.

Also, i figured removable would be best since no one probably wants to stay tethered.

I don't know if it's luck or my car, but just removing the cripple cap on the car and changing my car antenna to a Cat 5 that's about 5 inches long made my reception over 50 feet. It reached the end of my friends hallway that's over 50 feet long and ran out of space to go any further. Don't know how much further it will go, but I added a telescopic antenna to my controller. I wonder how far that will make it go.

blownPT · #**205** 03-12-2003, 12:12 AM

cat 5? care to clarify for me?

thanks.

Also, if that's true, I suppose the additional antenna wouldn't be necessary. But I think it also depends on where you are. certain places cause more distortion and interference than others. On a dead straight hallway with few obstructions, I would immagine there isn't much interference.

Also. can anyone verify that different frequencies results in different "performances"? maybe people can check in with that.

My brother was playing with his stock 49mhz microsizers against a 27mhz microsizers at school, and a little over half the distance out, the 27mhz cut out. (this is with high interference I would assume, all the metal chair and desk legs)

if anyone can tell me how I'm doing on my assumptions lemme know! Thanks~

Cat 5 = Networking Cable
There are like 8 wires in a standard network cable.

I was going to use a Cat 5 wire, but forgot it at home (Bits and tools kept at work, late shift is boring)
So I found a cable left over from a phone system upgrade marked: "General Cable Cat 3 Backbone 24 awg 12 pair"
This bad boy has 24 seperate solid core copper wires in it! Very rigid wires like the Cat5 which I like.

Removed the "crip cap" from the car, put a wire antenna slightly longer than twelve inched and did the "pigtail" look on it.
Now my cars (MS classic and MS Sport) will go about 40+ feet in the parking lot!

I have a few questions for the people that know about rf.

1. So it is just length that matters not height, when i think about a rf wave i would think a upsidedown L shaped antenna would work the best.

2. Does the antenna have to be able to coduct electrity? and if that is the only requiment then the pcb pen idea should work.

3. Stranded or Solid core, most people go solid but the person that seemed to know the most about this kind of stuff said that it gave more surfaces to chatch rf, which would mean shape and gauge would matter greatly, but then i have read the paino wire seems to work great

This is mostly speculation so dont take any thing i have said to be truth at least until someone backs me up...

Calsonic_racer · #**208** 04-09-2003, 09:41 PM

so overall after all these experiments which combo's do u think is the best? spring wire+alluminum foil internal antenna? copper wire+copper sheet internal antenna? or juss plain spring wire? and how long should it be?

vtheo · #**209** 04-10-2003, 12:00 PM

I have made a antenna out of wire from a motor its about half inch long, i decided that i wasnt going to use it( i dont want to solder in the little tiny bit) if someone wants to try it out i will post some pics. I was thinking it would be internal, but with my body its too snug (just glued front bumper back on) its coiled around q-tip stick that is cut to length

Duratrax · #**210** 04-11-2003, 01:06 PM

Im gonna make an internal antenna tooday... And plan using smth from an old capacitor
