Credit to Pak Halim and Azmeer for giving this plan and showing me how to construct a proper antenna. Hi there, sorry for being quiet for a while, but rest assured I was on some knowledge discovery mission to learn about building Slim Jim antenna for two way radio communication specifically for Amateur radio band.
This antenna is specifically built to resonates within 2 meter amateur radio band MHz. This antenna has been build with the help of my friend, Amet who is a trained electrician. Why build your own antenna? It is a way for me to better understand about radio wave resonance and to learn more about how to build a radio antenna to tune in to specific frequency, something that commercial antenna lacks, because it is built to tune to a wider range of frequency due to market demand.
This antenna is said to have a gain of 3. The reading is kinda bit off from the center of frequency :p, I know. However this is way cheaper than buying a commercial antenna which cost me a lot of bucks, and I surely have more fun! Supposed if you want the antenna to resonate better, you could replace aluminum tubing with copper or brass tube and replace RG coax cable with a low loss cable such as RG or RG-8 which was used in this experiment. Here are the photos of my homebrew 2 meter VHF antennas.

Make two holes at the opposite side of the pipe. This hole is used for putting the copper wire through the pipe. Repeat this step Both of these holes will hold the copper wire.
Insert the wire through the hole until both end reaches each other on one side of the PVC pipe. AI Control Panel. Barry's GPL Downloads. Create Hi Res Sky and Horizon. DATman View images in a dat file. GP Garage - Bandwidth Patch. GPL Carset Changer. GPL Coeff Checker.

This GPL track installer can be used to make it easier for people to install the nice track you just finished and want to release.
Alternative Track Installer by Bernd Nowak. This installer works in a very similiar way like the original from Martin Granberg. The difference is that the installer has no problems with the raised value of more then 64 tracks in season.

Pribluda v0. Pribluda is an essential tool for hotlappers as it provides split times and for online racing as it provides standings and time gaps to cars in front and behind you. This feature is very useful to make sure it is safe to leave the pits or to reenter the track after an off. The version only works with the older D3D rasterizer. If you run OGL, then get the updated version below. Unfortunately, no support currently exists for the new D3D v2 rasterizer. Pribluda v1.
This version includes some new features and also includes support for the old OGL Rasterizer. Pribluda patch by brr. This patch fixes Pribluda v1.
This utility checks to see what patches are installed and what the settings are for such patches as the More Cars patch. So if you used that you've already got it! This utility is to create custom output resolutions beyond the few that came with GPL originally.
