Whenever I come across suitable antennas for the low VHF bands, I try to keep a record of them here. I spotted this Log-Periodic beam recently on eBay...
This antenna is described as a 250w Transportable Log Periodic HF VHF Antenna 30-88MHz and it was sold in the past by SMC in Southampton, England.
As the photo shows above, it was probably destined for the military market.
Tactical, Anodised Green. SMC Part Number - TLP3088.
The specs above say it was 4m from the rear to front element and the gain was in the region of 6dBd. I suspect it was probably a bit less at around 5dBd but it would still be a fine antenna for anyone monitoring the low VHF spectrum from 30 to 88 MHz.
Keep an eye on the second hand market.
