I recently purchased a 421 Triband resonant end fed antenna from G-Whip Antennas.
The 421 is resonant on 40m, 20m, and 10m and has a total length of approximately12m from the feed point to the end insulator making it ideal to fit into a small garden, such as mine!
There are three different versions of the antenna available, all with different power ratings. I opted for the 150w version as I mostly operate digital modes, the two other versions are 400w rated and a 1000w rated version.
As with all G-Whip Antenna products this 421 end fed antenna arrived very quickly after purchasing and was well packed.
