After all, what kind of antennas should we take? If you were what would be your choice?                                                                      With the low values of SFI and the difficulties in transportation, what do we deserve?

Condition: The transport will have to be in a Golf Bag, from that point we have several options:

  • - Vertical antenna Force 12 XK40 10 to 40 Meters

  • - Vertical antenna Sigma I Pro Traveler 10 to 40 Meters

  • - Vertical antenna Antenna SQ9 10 to 80 Meters

  • - DXWire and VDA 12 Meter Mast Antennas 10,12,15,17 and 20 Mts and Vertical Ground plane for 30, 40 and 80m Meters

  • - Gustav Kelemen Dipoles 10 to 80 mts.

What kind antennas i shoud take ? free polls

Why i bring new antennas? My first few years as a radio amateur  were filled with gaping voids on many aspects of the art. One of these voids was the understanding of antenna operation relativ e to the makeup  of the fields forming  the radiation pattern , and particularly the vertical angle radiation. Participation during many years on URE Union Radioaficionados Españoles Congress  bropuight me  a greater deph  of understanding  in this area.  From QSO's on the bands  it becomes  apparent that other  Hams are  plagued with  the same lack of understanding. I i is itewnded

True Ground is difficult to find without extensive research and specialized equipment not usually available to the average amateur. In order to circumvent this obstacle  of true ground location, let us assume in all subsequent calculations that true ground is in the surface of the earth, is a perfect conductor, and will reflect the radiated  signal totally, without loss of energy..ntennas are a very popular s probably spends the most time talking about, both on a

nd off the air , is his antenna system. There are at least two good reasons for this, First,  the antenna  themselves  are pretty simple, at least from the  standpoint of circuitry. They contain No transistors, capacitors , resistors, diodes or even vacuum tubes or any kind of difficult circuit difficult to understand.  Antennas are usually simply pieces of wire  or tubing with perhaps a transformer thrown in for impedance matching . Thus, they are at least easy to see. The second reason for the great deal of attention antennas get  is their performance . Every ham who has been around very long knows that there is no easier way to improve his station's capabilities than to improve his antenna. When a significant change for the better is made in the antenna, the improvement in the station's ability  to communicate is immediately apparent, on both transmission and reception. One thousand Euros ( the usual price of store bought kilowatt amplifier on these days) spent on an antenna installation will do worlds more good for amateur than will a similar amount spent on a big "pair of boots" .   Also, antennas are very popular because they are easier to homebrew than most pieces of equipment . and easier  to make operate properly after their construction. Thus, the antenna deserves it's popularity. And if this so, then the simple theory behind the antenna  deserves to be understood by all of us. So, the reason for this comment -  will discuss the very simple theory of antenna gain, efficiency, capture area and effective height. These are subjects  of which very few amateurs seem to have a good grasp today. Much is heard about antenna "gain" especially, but few seem to have exact understanding of what they are speaking about. Perhaps this comment will help to clear up a little of confusion.

An antenna can basically be thought of as advice converting energy from one form to another. When an electromagnetic wave strikes as antenna we find that electrical power is available at its terminals. On the other hand, when we apply electrical power to the terminals of the antenna , we find that electromagnetic field  (wave) is radiated by the antenna.

This property of working both "backward and forward" is called reciprocity and is characteristic of antennas

Most of us  realize that it is Electromagnetic field s or "waves" that provide invisible link between transmitting and receiving stations in radio communications system. But the fact is that no one, even the professionals, knows just what a electromagnetic field is.

Short vertical antennas are of interest to many amateurs, Every mobile whip antenna is short, much too short, at frequencies, 7, 3.5Mhz. Also, not everyone is blessed with sufficient clear space for erection of horizontal dipoles at those frequencies, For such amateurs, the short vertical is a solution which may be attractive , especially for use on 40 and 80mts. this is a discussion  for those who care to know something about how such antennas can work, and what their limitations are. Since this type of antenna is electrically short, something as to be done to lengthen it so that will resonate and take power from the transmitter. One of the simple ways of resonating a short antenna is by use of a series loading coils.

I will take my I PRO Traveller Antenna and Vertical Wire Dipoles (VDA).He suggested that while he'd squeeze me in somewhere if it became necessary, he also had a well-equipped suitcase portable station Kenwood TS480S with internal tuner, and ALINCO DM33OMVE power supply.  I've permission for the antennas which perhaps I could operate from the cogttage? I scoped out the resort and found the perfect spot to string up the G5RV from a 4th floor stairwell window over to a convenient tree in the courtyard and our 2nd floor balcony was exactly half way in between. I thought long and hard about how to ask about putting up the antenna. In the end I decided it sounded better to describe it as 'a wire aerial for my radio' instead of a 'hundred foot long ham radio antenna'. I shouldn't have worrried. The owner of the cottage specialized in catering to their guests needs and the best line I heard on the whole trip was 'Are you sure you wouldn't like us to have the maintenance workers put up your antenna for you?' Now that's service! With the license in hand (it's actually a very official looking 10-page document, printed and bound!) and the G5RV hung in the garden it was time to get on the air. I had never used an Icom IC-7000 before but I knew what I wanted to do so after an hour of flipping through the manual I had the mic gain, ALC and compression set up and programmed the voice memories. 

Every body know that if you prefer one Manufacteur Equipment you never change if you prefer Yaesu, ICOM, Kenwood , Ten-tec etc, . We are talking about OM with some years on experience , myself I never change from Kenwood, i've already operate under diferent conditions or with Yaesu or ICOM even with TEN-TEC and Drake. We can start here a discussion, but i've a costumate to listening good reception on my Kenwood s ,that's the reason  KENWOOD Transceiver TS-480 DSP

Two filter slots in these radios allow you to choose two of the three available filters; YF-107CN 270 Hz narrow CW, YF-107C 500 Hz standard CW and YF-107SN 1.8 kHz narrow SSB. Each have excellent shape factor so you can capture just what you want to hear. Order your Kenwood Crystal Filters forKenwood TS-480 ...

I have instaled both 250 Hz and 500 Hz from ,    because I mostly do slow speed CW , and many of the station I communicate with uses older radio , their frequency often drift as time pass, and 500Hz is easier to tune,  only time I prefer 250 Hz filter is when there are a lot of noises from near by electronics power line , etc,  then 250 Hz remove more noise than 500 Hz filter,  my first choice would be 500 Hz , but I also like option of having 250 Hz as secondary

HEIL Headphones Model PROSET

The PRO-SET Headphones

This is also  great part of the equipment, I just tell you I've two pairs, one for my own  station and the other I've use to play radio on portable, DXpeditions also on Fieldays. Very confortable it's a great piece for DX'er with HC4 piece on Microphone works very well with all amateur equipments.When you use for the first time , you don't want to miss for other times, and help you on the pile-ups.
The Heil Pro 7 headset offers a feature set that compliments the Heil Sound standard for headset design. Unlike copies of various aviation type headsets, the PRO 7 is not a copy. It brings truly new technology to the headset industry. The 2" thick gel foam ear pads provide extreme comfort for extended periods of time while exhibiting passive noise reduction rated at -26dB which is ideal for use in high ambient noise environments. Using technology Bob Heil learned from Paul Klipsch back in the early 70s, the ear cup enclosures were tuned to the free air cone resonance of the speaker cone thus providing very low distortion with maximum voice articulation providing the ultimate sound reproduction for communications. The exclusive Heil Phase Reversal system (HPR) allows you to acoustically move the signals forward and creates a spatial widening of the sound field. This feature makes it easier to pull a weak signal from a pileup – useful for DxPeditions and contests as well as a stress reliever as your change the phase angle of the program source. A speaker balance control allows preferred level between the speakers.
