The most often bought antenna of the GAP family.
  • All 8 Bands from 10m to 80m incl. WARC
  • Length 7,5m
  • No radial required!
One of the primary virtues of the TITAN is the GAP center feed. The Titan is the only vertical antenna marketed with total continuous coverage under VSWR 2:1 on 10m to 40m and 100KHz bandwidth on 80m.
By elevating the feed the earth loss is dramatically decreased, which means the antenna operates independent from the earth conditions and may be installed either on a roof or close to the ground.
As is the case with all the other GAP antennas no further tuning is required.
The operating center frequency on 80m is set by means of an integrated fixed capacity. Please specify the desired center frequency upon ordering. The standard setting is 3.65 MHz, available are 3.55 or 3.7 MHz.
The TITAN requires no radials!




6-Band 40/20/17/15/12/10m
Length 6,5 m
The EAGLE is the smallest antenna in the GAP product line. The Eagle weights less than 9 Kg and can be installed almost anywhere - at ground level, on a pole, on your roof or atop a tower. It is essentially a set of vertical dipoles - the optimum singular DX antenna! No traps, coils or transformers are used to achieve multiband operation in this antenna either.
The EAGLE provides full coverage with VSWR < 2:1 on 40/20/17/15 and 12m; and approximately 500KHz on 10m without readjusting.
If the band is wide open, you might work a VK with a coat hanger, but when conditions are less than perfect you want the highest efficiency the antenna can provide. The efficiency of the GAP Eagle is without equal. It has no traps, transformers or matching coils to rob transmitted or received power. For the highest S meter reading, choose a GAP Eagle.
Three rigid counterpoises are required for operation (see picture) but no radials.




#8-Band 80/40/20/15/12/10/6/2m
Length 9,5 m
The Challenger is designed to be mounted directly on the ground or elevated on the roof. As is the case with the other GAP antennas since it does not require earth loss to obtain a 50 Ω match.!
Roof mount does not gain any specific advantage due to the 'elevated ground' structure, but is possible if there's no garden etc. available.
The CHALLENGER covers the bands 6/10/12/15/20 and 40m. Over 130KHz of bandwidth is provided on 80m!
The antenna requires a counterpoise of three 7.5m wires. They may be buried or just scattered on the ground. Symmetrical deployment is not critical. Adding additional wire will not significantly improve performance.
As described with the TITAN The operating center frequency on 80m is set by means of an integrated fixed capacity. Please specify the desired center frequency upon ordering. The standard setting is 3.65 MHz, other frequencies are available on request.




4-Band 160/80/40/20m
Length 13,5m
This is the first antenna manufactured specifically to provide efficient low band operation. Emphasis was given to 160m and 80m when designing the VOYAGER.
Unlike the Challenger, the VOYAGER employs a capacity hat with circular ring to reduce the physical height to 13.5m while maintaining an electrical height of 20 m. A capacity hat is the most efficient way to reduce height, maintain bandwidth and eliminate corona.
The entire band on 80m (!!), 40m and 20m, 90 KHz bandwidth on 160m.
As is the case with the CHALLENGER three insulated counterpoises of 17m are required, the deployment pattern is very flexible - also possible around corners.
Four guy anchor points 7.5m from the base mount are required. The guy brackets and aluminum pivot are supplied but not the guy rope itself.


Steel tube

Drawn steel tube made of ST 52, 32x3 mm, galvanized, fits the antenna joint. Cut to order, 1m to 2.5 m length and shipping together with the antenna through UPS.

Ground mount



Tiltable ground mount for digging in or fix in concrete. Enables quick tilt of the antenna (not required for model Voyager which contains a similiar base). For use with EAGLE and TITAN please specify the desired length of the steel tube. Order No.: No.: 23110 !
Ideal for the field day etc.
