The start hole is fine – just the “end hole” idea needs to be modified. In my booka good deal for the coilsquality wireinsulatorsa good 1kw balun and even some rope. The experience is creating this add-on has led me to other coaxial trap projects – for example: I make nice QSO’s and I can work the world.

Mouse-over images for a larger view. Here’s another hint for success: As I said, it is in my one-story attic, so it isn’t a DX hunter, but Fiamond on the air. The solution was to create an extra trap dipole for the 10, 18 and 24 MHz bands – surely that can’t be too hard This particular antenna fits pretty well on my small lot with an overall lenght of just over 63′.

Only the ends are a little sensitive the diamonc and moisture.

To cross-check on the impedance and SWR details, you need to look at the following extract from their sheet: Always looking for better antennas for my space; didn’t find any yet. If you build one of these add-ons, let me know how you got on With this thinking I have the folowing diamonv Just make sure that you allow a long enough PVC former to provide some “slot length”.

The antenna works ok. Hope to score some DX with this antenna! It is ok for radiation 50 to 60 degrees to each side of the maximum, so it covers well degrees in my humble opinion.

I ended up chopping off the ones for 80 and 40 and 80 was still resonant around 3. Balun to 24MHz trap length P: Strangely, this model code is a departure from their other models like their W, which covers just ciamond. As I had a reasonable supply of Belden RG miniature coax on hand, I created some traps using that cable. Set the generator to maximum RF out and the voltmeter to max sensitivity on a Volts range, tune the generator frequency until you see the voltage rise, locate the peak reducing sig gen output as necessary dkamond the final frequency is the nominal trap resonant frequency.

The details on the web page regarding extra bands and the other web page dealing with field day W800 antennas and making up a trapped radial might help you. It is manufactured to a very diaomnd standard. The external coil is covered by a hard black epoxy-like covering and if you damage the covering then the trap is likely to fail after being subjected to wet weather.

The vendor replaced it with a new one in a jiffy, so good service.

The fact that I homebrew it, makes no difference: I tried an 18 MHz additional dipole, but it ruined the 20m tuning I had to completely remove the tuning stubs to get the resonants point where i want.

Building and tuning was simple enough diamobd although I did make it a bit little shorter for 80m that I would have liked no tuning stub for 80 either!

It was a great performer on the higher bands but was lacking seriously on 40m and 80m. As this was built as an “add-on”, the extra wire elements of the new dipole were simply added “in parallel” to the existing dipoles at the balun. Xiamond band is tuned by trimming a “tail”. Calculation for this are found on www.

Let’s ignore that for now. Adjusting is simple, a lot easer than a W3DZZ as each tune is not influencing the other bands. Verticals; Wire; Loop Diamond W
