    not all loops require precise tuning..... this is most common with Small Tuned Loops commonly known as "magnetic loops". There are other designs that are more open minded. :D

    Covering 4 miles, even with low power is not usually much of a problem. Almost any antenna, as long as it will tune up correctly should do the trick.

    According to what is on QRZ, Poole Dorset would be his location. On 'flat' land ( not to be confused with 'flat' as in apartment ), 2 meters should also work. No mention of power levels was made. Here in 'the colonies', many portable radios will put out 1-7 watts with a charged battery- mobiles, 35 to 50 watts - stations, 100 watts. Since his signal is heard beyond, we can only guess that 'skip' or frequency separation is the issue. So then what is the SWR into the antenna system from the person who posted this 'thread'??? See posts #6 and #8... Magloop.

    80 M is a pretty good short hop Band but you need a lot of space since the dipole is 125 ft long. At 20-60 ft above ground you will get a pretty high angle hop... BEST for short distance work!
    When I was a novice, I ran about 4 Watts out of a single tube homebrew transmitter and worked mostly S. MI, N.OH and S. ON stations in the afternoons after school.
    I was using a dipole I made for 80 M , hanging from tree branches about 15-20 ft high.

    Rebuttal

    Keep in mind the repeaters do all the heavy lifting with high gain antennas on high office building roofs or big tall Commercial towers. :eek:Your 1 Watt hand held radio is nothing special! :rolleyes:

    40 is possible but 20 M is one of the "DX" bands and rarely does well in local comms.
     
    NQ1B and PU2OZT like this.

    Yes. Legal in the UK. Did that when I was practicing code.

    Hi,
    Well, lots of answers and choices.

    Things have actually gone off the boil, since this epidemic, and we've kind of lost touch as our radio club is closed. I'm sure once things calm down a bit, we can try some of the suggestions.
    It does seem starnge that we are finding difficulty. I think the hill in between us may contain some metal perhaps, as others in the clb are also in similar situations.

    Thanks. C.

    I'm late to the party, but I often participate in a CW practice net on 40M in the evening. When I was using a HamStick dipole, and then a 40M dipole at 8 feet above ground, the locals could hear me at S9+. I "fixed" my antenna situation by installing a ground-mounted vertical. Work a lot more DX, but the locals now hear me only about S 4-5. The low dipole is a good NVIS (Near Vertical Incident Skywave) antenna, and works better than most for short distances.

    Maybe try a low dipole, or even a loop on the ground.

    My radio club has suspended meetings, too. We do, however, meet weekly on the club's 2M repeater. Whatever it takes. . .

    Hi W,
    Mine's a 40MTr dipole, and his is a loop. There are others with this hill in btween, that have similar problems.

    Any of the locals have a bulldozer?
