A basic 5/8 wave base antenna with small ground planes (only about 1ft). A copy of the original Hygain silver rod.
In reality I think the ground planes are too small to really make any difference.
Made of tubular aluminium, supplied with U-bolts for mounting on a standard size pole.
We have found 5/8 wave antennas without large groundplanes do not swr as easily as a 1/2 wave, and my preference is to go for the 1/2 wave instead of this.
Made in the UK, these are sold under a variety of brand names and we will send whatever is currently in stock.
