Cheap & Cheerful Telescopic SPOTA Antenna
Available on eBay for around £45, this 5m whip with a ground spike and counterpoise/radial.
Sold as a QRP antenna, yet in the specs, quote it as ‘able to withstand 300W’, I think I will stay at 5-10W to be honest!
Well, I used it on two POTA activations on the 11th of November, coupled to my KX2 and internal ATU. You can obviously adjust the whip for best match, but I was lazy and left it at full height.
Most QSOs where on 20m and 17m. The seller quotes that it will tune 20m to 10m and I found this to be correct. It will also ‘tune’ on 30/40m, but don’t expect decent performance.
This is truly a cheap compromise antenna, but I was surprised how reasonable the build quality was! As you can see, it doesn’t take up much space, the aluminium ground spike is 10” long including the threaded portion.
The closed up whip is 20.25 “ including the threaded portion.
The ribbon counterpoise is also 5m long and is terminated with an eyelet that attaches to the ground spike threads. I did consider splitting the ribbon to make a fan pattern, but thought it would be pretty messy to deploy an store, I kept it simple and still achieved good results!
