Base Antennas (CB)

Homebase antennas for use on CB, which can often be retuned to work on 10 metres.

Most of these antennas are quite large (18ft and longer). We stock very few short base antennas for the simple reason that they don't work very well.

Don't forget to order your coax & plugs and any mounting brackets you may need to fit the antenna.

Discontinued - too expensive!

A high quality fibre-glass base antenna designed specifically to have a very wide bandwidth to cover all CB bands plus 10m & 12m without the need for tuning.

The antenna is approx 18ft long, claims a bandwidth of 8MHz (800 channels) and will handle a maximum of 2000W.

Probably the most popular antenna ever made for CB, a straight 18ft "silver rod" base antenna with no groundplanes.

Made of tubular aluminium, supplied with U-bolts for mounting on a standard size pole. Very easy to swr.

Made in the UK, these are sold under a variety of brand names and we will send whatever is currently in stock.

A basic straight 21ft "silver rod" base antenna with no groundplanes.

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.

A basic 1/2 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, so you are probably just as well having the basic 1/2 wave!

The original Solarcon A99 fibreglass antenna from the USA  (previously known as the Antron 99).

Our most popular higher priced antenna.

Very easy to erect, it comes in 3 sections which simply screw together. No screws or jubilee clips etc required.

Easy to swr - in most cases no adjustment is required, but if needed all you have to do is turn the tuning rings at the base of the antenna. Once in position simply lock the 2 rings together.

All 3 sections are also available as spare parts.

Please note that the brackets supplied with this antenna will only fit a maximum 1.5" diameter pole. If you wish to mount it on a larger pole (eg scaffolding) then you need to buy larger brackets with the antenna (eg. 2 x F25).

Groundplane Kit for A99

An optional groundplane kit to fit on the Solarcon A99.

The kit consists of 4 fibreglass groundplanes, approx 6ft long, and a mounting collar.
The collar fits at the base of the A99 and the groundplanes are angled downwards at approx 34'

Original Solarcon GPK, made in USA (not to be confused with cheap UK copies).

Original version - made in USA

A replacement top section for the Solarcon A99 base antenna.

Limited stock available of the original Firestik A99 upgrade. Made in USA.

Not only is this shorter than the original A99 top section, but also claims a higher gain because it is wound (like a Firestik) rather than just a straight wire.

Length 155cm.

Everyone who has used one has reported some gain over the standard A99.

New UK version

A replacement top section for the Solarcon A99 base antenna.

Originally these were made by Firestik and proved very popular, but they have not been available for several years now - so Thunderpole have now made their own version of it in the UK!

Not only is this shorter than the original A99 top section, but also claims a higher gain because it is wound (like a Firestik) rather than just a straight wire.

Length: 157cm.

Everyone who has used one has reported some gain over the standard A99.

Solarcon Max 2000

Previously known as IMAX 2000

A very long fibreglass antenna from the USA, the bigger brother of the Solarcon A99.

Very easy to erect, it comes in 3 sections which simply screw together. No screws or jubilee clips etc required.

Easy to swr - in most cases no adjustment is required, but if needed all you have to do is turn the tuning rings at the base of the antenna. Once in position simply lock the 2 rings together.

Personally I think this antenna is too large, it consists of 3 x 8ft sections (total 24ft) and does swing about a lot in the wind. But performance is about 3dB above the A99.

Gain-Master Hi-Tech Fibreglass Base Station Antenna for CB & 10m Band.

Gain-Master™ is a 5/8λ high tech fibreglass base station antenna for CB and 10m amateur band completely designed by electromagnetic simulation to achieve the maximum gain and optimize the radiation pattern and bandwidth.

Engineered with the most advanced available technologies it is completely manufactured in Italy with high quality materials.
The new design of the radiant element (Patent Pending) works like a central fed dipole so all RF currents on the radiator are in-phase and the ground plane radials are not necessary.
The coaxial coil at the bottom works like RF-choke for the optimum decoupling from mast and feeding line.
Made of telescopic fibreglass tubes, it is DC-grounded for the best protection from static discharges.

Gain-Master™ is the new reference standard in its class of antennas.

A very high quality 5/8 wave antenna with groundplanes. This is probably the best base antenna available.

Made from aluminium with Magnesium for better radio conductivity and maximum strength. This is certainly the strongest aluminium antenna available.

The large open coil prevents any build up of water or condensation and allows the antenna to handle high levels of RF power.

The top section is adjustable for swr, although in our experience there is usually no adjustment necessary.

Indoor / Outdoor

A compact base antenna for use either in the loft or outdoors.

Don't expect the same performance as a larger antenna, but if you really can not mount an antenna outside then this is an alternative.

If used in the loft it will simply stand on it's "legs", if used outdoors it fits on the top of a standard mast (35-40mm diameter).
