A friend and myself built more or less the same antenna as described previously:
In this case the antennas were all new. The interesting thing here is that the cost of the three simple antennas was actually somewhat competitive with the cost of a single complex antenna ($20+$20+$13=$53CAN). There is something to be said for creating a complex antenna out of simple parts particularly in the case of a difficult RF environment.
Here are the results:
| Channel | Strength | Quality |
|---|---|---|
| 7 | 90% | 90% |
| 13 | 78% | 98% |
| 27 | 100% | 100% |
| 35 | 75% | 86%-100% |
| 40 | 100% | 82%-96% |
| 51 | 100% | 100% |
The results for the two VHF-high band channels (7,13) are a bit worse than those described for the first antenna. That's probably because the new project used 5 element antennas. The original one used recovered 11 element antennas. Since we were paying for the antennas we settled for good enough.
These results were measured after a 4 way splitter as was the case with the first antenna. The new antenna site was 1 km west of the old one.
