The I-Pro Home
An effective yet simple vertical dipole requiring no radials or grounding
The I-Pro Home is a centre fed vertical dipole covering the HF bands between 40m & 6m. The high performance design uses efficient capacity end loading techniques to provide a low noise solution optimising performance, size and flexibility.
This is a slim, low windage profile antenna designed for use where space is limited and a low visual impact is important. There is no need for radial grounding wires which means that it is perfect for small gardens.
Measuring just 5m in height, it can be mounted less than 1m above ground so minimising the visual impact. The I-Pro Home is omni-directional so positioning is not important so long as the signal is not blocked by buildings or trees.
The 3.5kg antenna is easily lifted on and off the ground pole mounted fibreglass insulator rod when not in use. This means that the antenna can be out of sight and protected from storms and high winds.
The I-Pro Home is a non-resonant design which presents a very user friendly broadband match. Most modern transceivers have built in ATUs that will provide a match for 20m - 10m operation. An external ATU may be required for 40m and 30m bands and for transceivers without an internal ATU.
The band coverage includes 40m, 30m, 20m, 17m, 15m, 12m, 11m, 10m & 6m. Note 40m efficiency is down relative to the other bands.
