A dual band 802.11n antenna should not limit the functionality of the Intel 7260 Wireless AC Adapater. This is considered to be compatible.

The K40 will not work as a marine band antenna, as it is "cut" (optimised) for 26-30Mhz. The Marine Band of frequencies is usually found 156-174Mhz.
In IT field, dual band is associated with the wireless router. This router handles frequency bands of 802.11. Dual band routers support 11a users in 5GHz band and 11b/g users on the band of 2.4GHz.

The ideal length for a simple antenna is approximately 1/2 of a wavelength. At VHF FM frequencies this will be about than 1.5m long. On the AM band, a much longer whip antenna will be required (100m+). Not very practical. The ferrite rod is placed inside a coil of wire producing a simple loop antenna with the ferrite helping to intensify its magnetic properties producing a relatively compact antenna solution.
In order to reduce the antenna hight and to go long distant transmission
Equipment which allows a combination of multiple technologies (i.e. gsm, umts, and lte) and combination of dual or tri band widths. This allows to output through a single quad or hex port antenna.
Single-band routers use a 2.4 GHz and are limited in range and speed compared to dual-band routers, which use both the 2.4 GHz and 5 GHz band. Dual-band routers are more efficient, have longer range, are less prone to interference from household devices, such as microwaves and older cordless phones, and are faster.

Generally speaking, VHF or UHF radio. VHF is also used to communicate with ground personnel (heli logging, SAR, firefighting, etc). The 'system' consists of a radio, antenna cable, and external antenna. an intermediate antenna switch can be used to allow multiple radios of the same band to use the same external antenna.
A dual band wireless router is capable of transmitting and receiving signals in both the 2.4 GHz and 5 GHz radio bands. This ability was originally developed because the 802.11a and B wireless transmission standards used the 5 GHz band, while all subsequent standards switched to the 2.4 GHz band. A dual band wireless router is often used in business settings where the secure internal network uses the B standard, and other more general wireless services are provided with other standards.
