This is a preliminary experiment to compare the performance of two commercial small transmitting loops on 14 MHz. The loops were set up in a suburban garden, 20 metres apart. They were aligned with their nulls N-S and the loops were positioned N-S of each other to minimise coupling. The loops were approximately the same height above ground (1.2 metres). The loops were carefully resonated before use on 14.097 MHz. Each loop was fed with a WSPRlite transmitter set to 200mW 50% repeat rate. The experiment was carried out on 4-March-2017 from 0900-14:30z.

In this case, two identical loops have been used.

Note to self:

Ant 1 G4ZAY, WSPRlite 1, closest to house

Ant 2 G3CWI, WSPRlite 2, bottom of garden.

Results

Discussion

Radio conditions were generally poor with few spots. This experiment will need to be repeated a few times before any conclusions can be drawn.
