I am building a repeater at my fathers hose. Would this be considered a Land Station (in which the height is 20-200ft) or a Base/Control station (where it is limited to 20ft above the structure its mounted to). OR, am I even understanding this the right way lol. I am fairly new to this, and I am trying my best to stay within the regulations.
My basic question is what is the allowed height range for my antenna. I did some searching and found some conflicting answers, so i thought it would be best to just be safe and ask.

Reference: FCC Part95a - GMRS Rules and Regulations
95.51 Antenna height.
(a) A land station antenna (the land station's radiating structure (for
transmitting, receiving or both), including the tower, mast or pole supporting
it and everything attached to the structure) must not be a hazard to aircraft.
The licensee of a GMRS system must get FCC permission (see 95.83) before the
uppermost tip of an antenna may be higher than normally allowed in paragraphs
(b), (c) and (d) of this rule section.
(b) Regardless of any other requirement of this rule section, an antenna may
always be at least:
(1) 6.1 meters (20 feet) above the ground or above the building or tree
upon which the antenna is mounted; or
(2) equal to the height of an existing antenna to which the land station
antenna is attached.
(c) The antenna may be as high as 61 meters (200 feet) above the ground,
unless it will be within 6.1 kilometers (20,000 feet) of an airport or
heliport.
(d) If the antenna is near an airport or heliport listed in the FAA's (Federal
Aviation Administration's) Airport Facilities Directory, or near an airport or
heliport operated by the Department of Defense, it must not be higher than:
(1) One meter higher than the airport elevation for every 100 meters from
the nearest runway if the runway is longer than one kilometer (3281
feet), and is within 6.1 kilometers (20,000 feet) of the antenna; or
(2) Two meters higher than the airport elevation for every 100 meters
from the nearest runway if the runway is no longer than one kilometer
(3281 feet), and is within 3.1 kilometers (10,000 feet) of the antenna;
or
(3) Four meters higher than the heliport elevation for every 100 meters
from the nearest landing pad if the pad is within 1.5 kilometers (5,000
feet) of the antenna.
(e) If the FCC grants permission to put an antenna higher than normally
allowed in paragraphs (b), (c) and (d) of this rule section, the licensee may
have to mark the antenna with bright paint and light it up at night (see Part
17 of the FCC Rules).
(f) The antenna for a small base station or for a small control station must
not be more than 6.1 meters (20 feet) above the ground or above the building
or tree on which it is mounted.
