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.

Discounted prices shown are for current stock and can not be repeated once sold out.

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 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!

Solarcon A99

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).

Frequency 25-30MHz
Max Power 1000W
Length 5.3m
Radials optional

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.

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.

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

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 fiberglass 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 completly manufactured in Italy with high quality materials.
The new design of the radiant element (Patent Pending) works like a central feeded 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 fiberglass 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 large 7/8 wave base antenna, this is a copy of the famous Avanti Sigma 4.

Performance is very good, but because of the size of this antenna (about 28 ft!) it does bend a lot in the wind and is quite easily broken. We recommend that you use non conductive guy wires (eg fishing line) half way up the antenna to support it.

A very small (approx 1m) base antenna which can be used indoors or outdoors. Supplied with bracket and u-bolts.

This antenna will give very poor performance compared to other base antenna, and really is a last resort if you can not fit anything else. There is no groundplane required.

Expect a range of about 4 miles if mounted outside and possibly about 2 miles in the loft.

Swr is adjusted by changing the length of the coax. A cutting chart is provided and you must use the correct lenght of coax as listed (roughly mulitples of 9ft).

Probably the oldest and simplest antenna you could have - a basic 9ft + 9ft dipole.  Although these are supplied pre-tuned for 27MHz, they are easily modified for a wide range of frequencies.

These do work surprisingly well and are easy to erect. The only disadvantage is that they are weak and will break in the wind if used in an exposed area.
