I have just finished a delta loop for 40 meter and up.
My antenna house and garden is very similar this this :
after cutting and adjusting the antenna to 7.05 MHz i still get 2.8 swr at that frequency.
At 14.1 MHz the swr is 1.2 ! (so i guess the length is OK) and on 28.2 1,8 in swr.
The reports are excellent on 14 MHz and good on 7 MHz.
But i have a feeling that there is something wrong on the 40 meter band.
The antenna of this type should hang around 1/8 wave length above ground (5 meters)
On same pleases i am down to around 3,5 meter so the height is between 5 and 3,5 meter.
One of the 4 legs of the loop is about 1 to 1,5 meter from the rain catcher (metal).
Is the high swr on 40 meter because of this ?
or since the swr i 1,2 at 14 MHz it is an indication of that i need the antenna higher up.
Is the high swr on 40 meter because of the height above ground is to low ?
