Quad Band Mobile

-

Ive been quite busy this week with a lot of driving it worked out well as I got the opportunity of playing radio /mobile, I have the choice of 4 bands with the antenna systems i have installed to my Toyota rav 4.

The picture above shows a Diamond 2m/70cm ANT, a 40m Maldol HFC40, and a 20M Maldol HFC20.

This weeks QSO from the mobile have been made on 20m and 40m, the most of the time I was operating on 40m with some excellent results on my ft100 running 50 watts.
I made contacts with Italy, Spain, Netherlands, Germany, Norway and Poland all on 40M and from the Mobile. I am once again impressed with the performance of the little Maldol HFC40 like its partner gripped to the back of my tail gate the HFC20, both of these antennas have been in use daily for over 2 years and are still in top shape providing an experience of pure joy and surprise with some of the distant Counties worked.

I have one of the 80m Maldol HFC80 but I haven't managed to make QSO with anyone so I wouldn't recommend that one. The 15 meter comet can be installed quickly replacing one of the others, again this antenna has proved to be a good radiator. The Toyota roof has two large removable roof panels made from aluminium so I wouldn't be surprised if the Aluminium assists with my transmitted Waves helping them to radiate successfully from my Vehicle.

Ive got some Good Mobile touring coming up so I am looking forward to meeting you all on 40M, 20M, 2M & 70CMs whilst I tune around the bands on my journeys :-)

Hello Simon,
(kon ni chi wa Simon san.)

What a wonderful your HF working from your mobile station, Simon. It is great! And it has hit me your HF antennas were working many many years on the mobile station. Because I like "any TOOLs" that give me special benefit when it is difficult to do something by myself. For example, knives,pliers,bicycles,cars and this personal computer, with which I am writing my messege for you.

Of course, Rigs and Antennas, too.Your comment make me glad and happy, Simon.It is my pleasure!

So, I will be very happy, I think, when I actually call your 2E0HTS on the HF band with my TOOLs, rig and antenna. Ham Radio, it's wonderful! (^-^)

2E0HTS, ko chi ra wa JN4VWH from Japan!!!! 73

Full Size Delta Loop for 20M

Image
I came across a simple delta loop design courtesy of dxzone found on the net some time ago and have been planning to give it a go for a while. This weekend I had a couple of hours spare, so I decided to give it a go using some 2mm multi strand wire cable, a dipole centre and a mixture of 75 ohm and 50 ohm coaxial cable. The delta loop is supposed to be resonant on 20 meters but I found it to be a little high so at present I am tuning the Loop with my mfj-969 which copes extremely well. The resonant frequency is 13.2 MHz at the moment so the next chance I get, I shall shorten the overall length making sure that each of the three sides are still equal in length, and hopefully adjusting the antenna for maximum performance ATU free for 14.2 MHz. I believe the miscalculation in the resonant length is probably down to the fact that my wire is covered in the plastic sleeving from the manufacturer which always effects the swr as I have noticed in past experiments with dipoles you always get sl

Homebrew 40/80 Trap Dipole Design

This Antenna design was one that I used about 4 years ago, it worked exceptionally well on 80m and 40m. The size of the antenna makes a Half wave length on 80 meters, and with the traps a half wave on 40m with a SWR (standing wave ratio) of 1:1-1.5 across both bands. It worked well also on 20m with the use of an A.T.U (antenna tuning unit). I made my version of this antenna using 3mm multi strand copper cable which I left covered by the PVC insulation. The traps can either be home brewed using some 40mm diameter plastic drain pipe and winding wire around the pipe approximately 10 turns, then connected in line after the 10 metre lengths. Or the alternative is to purchase some commercially made 7.1 MHz traps, and fit them in line the same way. The antenna can be fed with 50 ohm coax with a home brew balan or again a commercially purchased balan. The wire lengths of the dipole are 2x 10 metres and 2x 6.7 metres as shown on the diagram above. This antenna can be mounted quite low to the gr

New DX Contact 0n 12 Meters

Today I managed a nice QSO with Tom ZD7X who is located at St. Helena which is quite a distance away from my location. I managed to work Tom ZD7X with a 5/9 report operating my FT-767GX with my home brew 20m delta loop assisted with the MFJ-969 to tune the antenna with 50 watts on 12 meters. 12M is rarely open and I have only had a few QSOs on this band so I guess the new Cycle has begun at last! Good DX de 2E0HTS 73
